Steyr AUG with HBAR Barrel

Sometimes all is not as it seems. That was the case when we examined this Steyr AUG. From the barrel and bipod it appeared to be an AUG in an HBAR or Heavy Barrel configuration but on closer inspection we found that it was in fact a rifle receiver, bolt and bolt assembly and chassis that had been paired with an HBAR barrel assembly.

Ordinarily, the HBAR could be modified to fire from an open, rather than closed, bolt. This example has the standard AUG progressive trigger for semi and full-auto. It does not have the modified bolt carrier, striker or trigger mechanism.

The HBAR has a 4x optic, rather than the rifle’s 1x, while the HBAR-T can be fitted with an optic like a Kahles ZF69 6×42.

Adoption of the AUG HBAR does not appear to have been widespread and Steyr don’t currently list it as an option amongst their upgraded AUGs. For more Steyr we have previously examined a Steyr AUG SMG conversion and a Steyr MPi 81.

Winchester 1866 Prototype Musket

Today, were taking a look at a Winchester prototype developed in the mid-1860s, a period when Winchester was seeking to build on the success of the 1860 Henry Rifle and place the company on a firm financial footing. Oliver Winchester had taken control of the New Haven Arms company before the Civil War and while for a time it had been known as the Henry Repeating Arms Company he eventually sought to put his stamp on the company, renaming it Winchester Arms Company in 1866. At the same time he decided to focus the company’s energies on winning military contracts around the world.

This developmental prototype is in the ‘musket’ configuration: with a longer barrel, a bayonet lug and a wooden forend. The prototype represents one of the many developmental steps towards what would become the Model 1866. It has a number of interesting features – a steel, rather than brass, receiver and a hinged loading port developed by Nelson King, Winchester’s superintendent between 1866 and 1875.

The rifle itself was built by Luke Wheelock, Winchester’s model room mechanic and a designer in his own right who would go onto develop his own rifle designs for Winchester.

US55012-drawings-page-1.png
King’s 1866 patent (US Patent Office)

The rifle is 54.5 inches long, with a 33.75 inch barrel. Believed to have been built in 1866, it is chambered for a .45 calibre rimfire round. King patented his loading port in May 1866. He described how the port worked:

“Through one of the plates S (preferring that one upon the right-hand side) I form an opening, 0, as denoted by broken lines, Fig. 1, and also seen in section, Fig. 7. This opening is formed so as to communicate through the frame directly to the chamber E in the carrier block, as seen in Fig. 3. Through this opening, and while the carrier-block is down and all parts of the arm in a state of rest, insert the cartridges, point first, through the said opening in the plate S into the chamber E the second cartridge pressing the first into the magazine, and so on with each successive cartridge until the magazine is filled, or until the requisite number has been inserted therein, the follower G being pressed up before the entering cartridges. In the rear of the chamber E2 the frame forms a shoulder to prevent the cartridges from being forced out through the opening in the plate S3 is a cover for closing the opening in the plate S3 and is hinged thereto, as seen in Figs. 1 and 7, the hinge being provided with a spring,a1, the tendency of which is to open the cover C. A spring-catch, d, (see Fig. 1,) secures the cover when closed, so that by pressing upon the said catch the cover will fly open. After the requisite number of cartridges have been placed within the magazine, close the cover, as seen in Figs. 1 and 2.”

To paraphrase: ammunition can be loaded through the opening in one of the receiver side plate when the carrier block is down, insert the cartridges through the opening, pressing the first into the magazine and so on until the magazine is filled… a cover for closing the opening is hinged to the receiver side plate. A spring catch secures the cover when closed.

According to Herbert Houze, King developed the covered loading port design in early January 1866, with a design drawing dating to the 14th January, confirming this.

Nelson loading gate cover prototype 1866 - CFM.jpg

King altered the design of the rifle’s cartridge carrier so that a cartridge could pass through its lower section straight into the magazine when the action was closed. In theory the aperture could be placed on either side of the receiver, in practice is was placed on the right. Prior to this Winchester had experimented with systems where the tube could slide forward (G.W. Briggs US #58937), a port in the base of the receiver (J.D. Smith US #52934) or a sliding forearm covering a loading port at the rear of the magazine tube (O.F. Winchester UK #3284 [19/12/1865]).

DSC_0686
A look inside the hinged loading gate (Matthew Moss)

King’s system had the benefit of allowing the rifle to be quickly loaded or topped off without rendering the rifle unusable while loading. Positioning the port in the receiver allowed the magazine tube to be enclosed by a wooden forend.

A cartridge guide was fitted inside the receiver which guided rounds through the cartridge carrier and into the tube magazine. The rounds were prevented from popping out of the magazine, when the carrier was aligned and the cover open, by a shallow shoulder which projected in line with the carrier’s channel to hold cartridges in the tube by their rim.

DSC_0685
The musket with its action open, bolt to the rear and loading gate open (Matthew Moss)

The hinged cover is held shut by a spring catch mounted on the rear of the cover. When the knurled section on its front is pressed rearwards the cover pops open. The spring catch is actuated when it tensions against the cover’s hinge as it is closed. On the back of the cover there is also a cartridge stop for when the cover is closed.

Another small but interesting feature of the prototype is the catch at the rear of the lever loop, this differs from the manually turned catch seen on the Henry and production 1866. This design appears to be a much better safety feature, simply requiring the user’s hand to depress the catch to unlock it from the stock. It also appears to be a much simpler mechanism than that seen in later models like the Model 1895. The trigger also had an extension protruding from its rear which appears to prevent the trigger from being pulled when the lever isn’t full closed. Neither of these features appear in King’s May 1866 patent.

It appears that the idea of the port with a hinged cover was superseded by what we now recognise as the classic Winchester loading gate in the summer of 1866. King’s new system replaced the hinged cover with a piece of stamped spring steel attached to the inside of the receiver side plate by a screw. The spring steel gate could be pushed in, with the nose of a cartridge, to allow rapid loading. The front face of the gate formed a cartridge guide removing the need for the separate machined guide used in King’s earlier iteration of the system.

King’s revised loading port system required just five, rather than twelve, components: King’s altered cartridge carrier, receiver side plate, spring metal loading gate plate and retaining screws. This simple but elegant design continued to be used for decades on various models of rifle. The company were so pleased with the refinement of the rifle that, according to R.L. Wilson, King was awarded a payment of a $5,000 reward by the company’s board of directors.

Winchester introduced the rifle in 1866, with the first deliveries being made early in 1867, the new rifle was offered in various barrel lengths and patterns including carbine, rifle and ‘musket’. Winchester found some success selling 1866 rifles to the militaries of France and the Ottoman Empire, while many other countries purchased rifles for testing including Britain and Switzerland (whom came close to adopting the Winchester.) The rifles also found success on the civilian market with around 4,500 sold in the first five months.

The Scientific American described the new rifles as “elegant in appearance, compact, strong, and of excellent workmanship. On examination we find its working parts very simple, and not apparently liable to derangement.”

King incrementally developed his loading system before radically simplifying it and this prototype rifle represents an important developmental step in the design of what would become the Model 1866 – one of Winchester’s most important rifles.

Madsen M50 – Live Fire

The M50 is one of the quintessential early Cold War submachine guns. Cheap, simple and utilitarian. It evolved from the earlier M46 and was developed by Dansk Industri Syndikat in Denmark. The M50 has a simple blowback action, is chambered in 9×19mm and feeds from 32-round double stack single feed magazines.

The weapon’s has a clam-shell like receiver that hinges at the rear and allows the barrel, bolt and recoil spring to be removed. The M50’s folding stock has a leather cover and while the length of pull is a little short it provides a decent cheek weld.

New Movie (2).Movie_Snapshot
Madsen M50 (Matthew Moss)

The M50 has a relatively slow rate of fire of around 500 rounds per minute which makes it very easy to make single shots while in full-auto. The sights are extremely simple with a single rear peep sight.

It has manual safety switch on the left side of the receiver which locks the sear in place and a spring-loaded grip safety just behind the magazine well. The amount of pressure needed to disengage it is minimal and a firm firing grip of the magazine is all that is needed. 

DSC_0242 (1)

The Madsen went through a number of changes with various models having different magazine release types, selectors and manual safety positions. The M53 introduced in 1953, fed from a curved magazine and had an improved magazine release. Some models had an additional fire-selector and the safety moved back above the trigger. Some models retained the forward grip safety while others moved it to behind the pistol grip. Some patterns of M53 also had a barrel shroud for mounting a bayonet as well as added wooden panels on the pistol grip.

Remington’s Hybrid .303 M1903

In 1940, following the evacuation from Dunkirk the British Army was in desperate need of small arms, with over 100,000 rifles left behind in France. In dire need of rifles Britain turned to the US and its huge industrial base and approached a number of companies about tooling up to produce Lee-Enfield Rifle No.4s. Savage Arms took on one contract and projected production of 1,000 per day but establishing production of a rifle US companies didn’t have the tooling and gauges for would take time.

remington_1903_303_rightwm
Right side of the Remington (Matthew Moss)

Remington was also approached by the British Purchasing Commission and asked if they could manufacture up to 400,000 rifles. Remington estimated it would take up to 30 months to tool up for No.4 production. However, Remington believed that if they could lease the old tooling previously used at the Rock Island Arsenal to produce M1903s, from the US Government, they could tool up to produce the M1903 in just 12 months. It was suggested that the tooling be adapted to produce rifles chambered in the British .303 cartridge. Some ergonomic changes could also be made so the rifles mimicked the British No.4.

remington_1903_303_leftwm

On 12th December 1940, the British government issued a Letter of Intent to Remington for the manufacture of 500,000 rifles in .303 British. Some sources suggest the British agreed to an advanced payment of $4,000,000. Much of this covered the lease, transport and refurbishment of the M1903 tooling. The rest went on the purchase of raw materials and the necessary accessories for half a million rifles.

The tooling lease was agreed in March 1941, and the US Government also supplied 600,000 stock blanks which had been in storage in exchange for ammunition produced by Remington. With the passage of the Lend-Lease act, on 11th March, the Remington contract came under the control of the US Government, rather than a private order. Remington received the last tooling shipments from Rock Island Arsenal on 22nd April, and by the end of May had the production line up and running.

A contract to produce the hybrid rifles at a cost of $5 per rifle was agreed in late June. Remington’s engineers began setting up the equipment and working out an ad hoc production layout that would allow 1,000+ rifles per day to be built. At least four pilot models were built, with some of these guns being sent to Britain. The rifles were reportedly received in September 1941, and following preliminary examination were described as “very successful”. Four of the rifles were distributed for further testing but by the end of 1941 the project had been abandoned.

A close up of the adapted muzzle and foresight so the rifle could fit a No.4 bayonet (Matthew Moss)

Remington made a number of external and internal changes to approximate the British No.4. They fitted a front sight post with sight protectors which was moved further back from the muzzle to enable the rifle to mount a Rifle No.4 spike bayonet. As such the upper barrel band does not have a bayonet lug.

Many of these parts are still in-the-white, unfinished, including the barrel, barrel bands, floor plate, front sight assembly, rear sight assembly and the bolt itself. The bolt does, however, have a parkerized cocking piece.

The hybrid also moves the rear sight back onto the receiver, which necessitates a longer piece of wooden furniture covering where the M1903’s ladder sight would normally be. The style of rear sight was also changed to a two-position flip sight with apertures for 300 and 600 yards mimicking those seen on the No.4 Mk2.

DSC_0541wm

They also redesigned the charger guide to support the Lee-Enfield-type chargers rather than the M1903 stripper clips. The bolt was adapted to work with Britain’s rimmed .303 round, with the extractor modified for the British cartridges wider, thicker rim.

DSC_0527wm (1)
A close up of the bolt head (Matthew Moss)

The rifle did not have the Lee-Enfield’s detatchable box-magazine, instead retaining the M1903’s 5-round internal magazine. The magazine follower does not appear to have been altered either. Markings on the rifle are minimal and include a ‘7’ on the front sight post, a ‘B2’ on the bolt handle and a ‘2’ stamped on the magazine follower. No roll marks or serial numbers appear to be present.

DSC_0533wm
The faux Lee-Enfield stock with spliced in semi-pistol grip (Matthew Moss)

The rifle’s stock has also been adapted, so instead of a straight wristed-stock a piece of wood has been spliced in to create a Lee-Enfield style contour, forming a semi-pistol grip. The stock is marked with the inspector marks ‘WJS’, which indicate the stock was originally inspected by W.J. Strong and accepted between 1918 and 1921, as well as a pair of later Springfield Armory inspection cartouches: ‘SPG’ – the initials of Stanley P. Gibbs, who was an inspector at Springfield Armory between 1936-1942 and ‘GHS’ – the initials of Brigadier General Gilbert H. Stewart (GHS), Springfield’s commander in the late 1930s- early 1940s. This would suggest that the stock was refurbished at Springfield Armory before being transferred to Remington where it was subsequently adapted.

DSC_0531wm
A detail shot of the stock’s Ordnance stampings (Matthew Moss)

In August 1941, the US began its re-armament programme and in September the British contract with Remington was cancelled. At the same time production in Canada and at Savage’s J. Stevens Arms division in the US had gotten underway and it was decided that the adapted hybrid .303 M1903s developed at Remington was no longer needed. The hybrid contract was formally cancelled in December 1941, and additional .30-06 M1903s and M1917s were taken under the Lend-Lease Agreement to fulfil the needs of the Home Guard. Savage believed that they could significantly increase the number of rifles they could build per day, they managed to enter full production by the end of 1941 and by 1944 had produced well over 1 million No.4s.

1903A3

Remington went on to produce M1903s for the US military, overcoming issues with the original engineering drawings and the tooling dimensions to eventual produce 365,000 M1903s by mid-1943, before switching to production of the M1903A3 pattern and producing 707,629 rifles. In total Remington produced 1,084,079 M1903-pattern rifles during World War Two.

The Remington .303 M1903 hybrids are perhaps the rarest M1903 variant, with only a handful built. They would likely have been perfectly serviceable rifles and helped plug the desperate gap in Britain’s arsenal. Rapidly moving events ensured that these rifles became a footnote in both the Lee-Enfield and Springfield 1903’s histories.

Special thanks to both Remington and the Cody Firearms Museum for allowing us to take a look at this extremely rare rifle.

The Sten Gun, Its Name and the Men Behind It

The Sten is one of Britain’s iconic Second World War Small arms. Two men are principally responsible for its development Colonel Reginal Vernon Shepherd and Mr. Harold John Turpin a pair of small arms and engineering experts with considerable experience.

Turpin was born in Kent in 1893, served his apprenticeship as a draughtsman in Erith and in 1922, he joined the drawing office at the Royal Small Arms Factory Enfield – Britain’s principal state small arms centre.

Reginald Shepherd was born in 1892, received an Bachelor of Science Degree from Leeds University in 1912. In October 1914, he joined the West Yorkshire Regiment as a second lieutenant, serving in Gallipoli and Egypt. After the war, with his engineering background, he assigned as 2nd Assistant Superintendent at the Design Department at RSAF Enfield in December 1922, and promoted to captain.

The two men found themselves joining Enfield at around the same time. In November 1933, Shepherd, now a major, was appointed Inspector of Small-Arms (Class 2) at Enfield and assisted in getting the Bren light machine gun into service. He remained at Enfield until 1936, when he retired from the army and spent a short spell at BSA before being recalled. In late 1939, Major Shepherd returned to active service and once again took up the position of Inspector of Armaments, this time at the Ministry of Supply Design Department at Woolwich Arsenal.

Inside RSAF Enfield (Royal Armouries)

By the outbreak of the Second World War Turpin had become the senior draughtsman at Enfield and when the development of the Lanchester Machine Carbine began he was paired with Major Shepherd to draw up technical drawings for the gun’s production.

The two men decided that a simpler, cheaper submachine gun could be produced and in December 1940 set about designing it, with Turpin in the lead. During the Winter of 1940-41 the first prototypes were built. Development of the first Sten – the T40, was completed on 8th January 1941, taking just 36 days.

14 pilot models were ordered but only two were completed by engineers at the Philco Radio Works in Middlesex: T-40/1 and T-40/2. The gun was initially designated the ‘T-40’ or Turpin, 1940. By the end of January 1941, it had become known as the ‘ST Machine Carbine’. The ‘Carbine, Machine, STEN, MkI’ was approved for issue on 7th March, 1941, with 100,000 guns ordered.

How did the gun become known as the ‘STEN’ and what did Sten stand for?

We know that the ‘S’ stands for Shepherd and the ‘T’ for Turpin, but what about the ‘EN’ – it is generally accepted to represent ‘Enfield’. Why? Because RSAF Enfield is synonymous with British military firearms. Additionally the Bren light machine gun’s name is a portmanteau of ‘BR’ from Brno, the location of the Czech factory the zb.26/30 originated from, and ‘EN’ for Enfield, the British factory that anglicised the design for British manufacture and service.

Enfield, however, wasn’t where the Sten was designed. Turpin and Shepherd claimed that most of the work on the design had been done out of hours. Additionally, during the winter of 1940, the Armament Design Department was relocated, from Enfield to a former Drill Hall in Cheshunt, Hertfordshire to escape the bombing of London.

While the Sten may not have been designed at Enfield, the first prototype was partially assembled there with work also done at Turpin’s own home workshop. A further 46 pre-production pilot models were later ordered from RSAF Enfield, in February 1941.

name insert

Intriguingly, early accounts suggest that ‘EN’ may have stood for ‘England’ – not ‘Enfield’. In October 1942, the fifth instalment of ‘Know Your Weapons’, a semi-official series of weapons manuals printed by the publisher Nicholson & Watson, explains that ‘EN’ did in fact stand for ‘England’.

In June 1943, Turpin penned a semi-anonymous article for ‘The Model Engineer’, about the design and development of the gun, which repeated this claim. An October 1943, article in the US Popular Mechanics magazine, entitled ‘Machine Guns from Backyard’, includes a supposed quote from the inventors explaining that the “E and N stood for England.”

‘The Sten Carbine’, Model Engineer, Turpin, June 1943

A more official account came in June 1949, at a hearing of the Board of the Royal Commission Awards to Inventors (a board set up to reward inventors who had done important war work). One of the board members Lord Justice Sir Lionel Cohen asked Shepherd: “Why was it called the Sten?” The colonel replied: “It was called the Sten by the then Director General of Artillery. The ‘S’ was from my name, the ‘T’ from Mr. Turpin, who was my draughtsman and who did a very large amount of the design, and the ‘EN’ was for England. That is the origin of the name, for which I accept no responsibility.” This suggests that the ‘EN’ standing for ‘England’ may have originated from the upper echelons.

Sadly, there was no officially published explanation of the name as official manuals rarely go into superfluous detail. In 1948, however, Ian Hay published R.O.F. The story of the Royal Ordnance Factories, 1939-1948 in which he stated the ‘EN’ was a reference to the Enfield factory. Similarly, another early published account, D.M. Ward’s 1946 The Other Battle, a history of BSA, also suggested it represented the factory name.

In truth it is difficult to know exactly what the ‘EN’ stood for. It may be that both Enfield and England were discussed and used by various individuals and offices. There may have been an element of propaganda to including ‘England’ in a weapon’s name which led senior officers to push this in the press and direct the gun’s inventors to suggest this was the case too. Of course the authors of those earlier books may have mistakenly believed ‘EN’ stood for Enfield, as it does in Bren. Personally, I’m inclined to follow the primary sources attributed to the two men responsible for the design, and believe it initially stood for England.

Other War
The Other Battle, D.M. Ward, (1946)

Shepherd was awarded an OBE in January 1942, and became the Assistant Chief Engineer Armament Design (A/CEAD), he was promoted to Lt. Colonel in August 1943. He retired from active duty at the age of 55, in January 1947, and was removed from the reserve list. He was granted the honourary rank of colonel. He died in April 1950, aged 58. Turpin retired from RSAF Enfield in 1953, and died in April 1967, aged 74.

Beyond a pair of discretionary payments, £1,500 to Shepherd and a small payment of £200 to Turpin, neither man was officially rewarded as they were deemed to have essentially done what they were paid for, designing small arms. Scant reward and recognition for a weapon which became one of the key wartime small arms of the British and Commonwealth forces.

Our thanks also to Jonathan Ferguson, of the Royal Armouries, for sharing his thoughts on the ‘Enfield’ vs ‘England’ debate.

A Walk Around the Cody Firearms Museum

Last summer I had the chance to visit the newly renovated Cody Firearms Museum. With the ongoing Coronavirus Pandemic I thought now was a good time to finish my walk-around video taking a look at the new museum.

The museum has always had an extremely impressive collection of firearms and gun related artefacts, some of which we’ve been lucky enough to feature in videos, but the new museum puts more of these amazing firearms on display than ever before.

One of the features I really liked was that many of the cases can be viewed on both sides allowing you to see all around the firearms.

Around the exhibits are touch screens where you can call up more information, first hand war stories and even animations of how various firearms work.

Steyr MPi 81

Developed in the late 1960s and introduced in 1969/70 the MPi 69 was Steyr’s entry into an already crowded European submachine gun market. Heavily influenced by the Israeli Uzi it had a bolt which telescoped over the barrel and fed from a box magazine that was inserted through a magazine well-come-pistol grip.

The MPi 69 weighed 6.5lbs (2.93kg) unloaded and had a polymer lower receiver into which a stamped metal upper inserted. Unlike the Uzi it had a collapsing, rather than folding stock, similar to the M3 submachine gun’s, and was cocked not by a handle but by pulling the sling (which was acted on the bolt) to the rear.

The MPi 69 remained in production into the early 1980s when it was replaced by the improved MPi 81. Moving away from the slick-cocking ‘gimmick’ the MPi 81 had a conventional, non-reciprocating, charging handle on the left side of the receiver. The MPi’s polymer lower allows it to be a pound lighter despite being slightly longer as a result it also balances better than the standard Uzi carbine.

The MPi submachine guns fed from 25 or 32 round box magazines and both guns had a heel-type magazine release paddle in the base of the pistol grip. They also shared their magazines with the AUG 9x19mm submachine gun conversion. Check out our earlier video on the Steyr AUG conversion here.

The MPi submachine guns fire from an open bolt and had a 10in barrel and has a push through safety with settings for safe, semi and full auto and unlike the Uzi it does not have a grip safety – simplifying manufacture.

The MPi also has a progressive trigger which when set to full-auto will allow the user to fire semi when pulled to the first stage and full when pulled fully to the rear. While the MPi 69 had a cyclic rate of around 500 per minute, the MPi 81 increased this rate to ~750rpm.

The MPi can be field stripped by simply rotating the receiver end cap up 90-degrees and pulling the bolt out the rear. The gun can be further stripped but the moulded polymer lower receiver can be difficult to remove from the upper. Like the Uzi the barrel nut is unscrewed to remove the barrel.

It is unclear just how many MPi submachine guns were produced but they didn’t see any significant contracts beyond a few small sales to police forces and militaries.

The MPi 81 remained in production into the early 1990s when it was replaced by the smaller and more compact Steyr TMP in 1992. In turn the TMP design was sold to B&T a decade later.

Hotchkiss Type Universal

 

The need for compact weapons capable of being carried with ease by troops who would be getting in and out of vehicles, jumping from planes and fighting in close quarters had been proven during World War Two.  While it may look unusual the Hotchkiss ‘Type Universel’ was an extraordinary attempt at creating an extremely compact submachine gun.

Submachine guns had proven themselves to be an useful weapon during the war, their small size and high rate of fire made them invaluable, especially in close-quarter situations. The post-war French army found itself armed with a plethora of surplus submachine guns, which included: the German MP40, the British STEN and the American Thompson as well as their own pre-war MAS-38s, in 7.65x20mm Longue, which had been designed before the war. By 1946 they had already begun the process of selecting a new, more compact submachine gun. Seeking to standardise on a single weapon and calibre they selected 9x19mm and launched a programme to find a new submachine gun or Pistolet Mitrailleur.

The French War Ministry launched a call for state arsenals and civilian manufacturers, such a Hotchkiss and Gevelot/Gevarm, to submit submachine guns for trials. Hotchkiss submitted the Type 010 or Type Universel, often anglicised as Universal, despite this the guns are typically marked ‘CMH2’ – ‘Carabine Mitrailleuse Hotchkiss’.

Chambered in 9x19mm, the Hotchkiss fed from MP40-pattern magazines, used the ubiquitous blowback action, it fired from a closed bolt and had a cyclic rate of approximately 650-rounds per minute. The Hotchkiss is select fire with a push through selector that allows for semi and full-auto fire. It appears that the weapon’s only safety mechanism is to close the ejection port cover and lock the bolt in place – much like a US M3 Grease Gun.

Designers went to extraordinary lengths to minimise the size of the Universel. Not only did the stock fold beneath the barrel but the magazine well and magazine could be rotated forward to sit beneath the barrel with the magazine fitting between a U-shaped cut-out in the butt stock. The weapon is a curious mix of stamped metal and complex machining with a difficult to machine bolt and barrel contrasting with a stamped sheet metal lower receiver and wide stamped trigger.

In 1950 Hotchkiss sales material described their weapon as “the individual defense weapon meeting the requirements of the most modern Armies and Police. Folded up, it is very compact, easy to transport, conceal and parachute. It is quick to set up and comes unfolded in the form of a carabiner…”

The weapon’s pistol grip was hollow and when folding up the stock, the grip folds forward to cover the trigger. The Universel’s most interesting feature is its telescoping barrel which retracts several inches inside the receiver. These features brought the Hotchkiss’ length down from 30.6 inches (77.6cm) when the stock was extended, to 22 inches (54cm) with the stock folded, and an impressive 17.25 inches (43.5cm) when fully collapsed. The nature of how the pistol grip folded with the stock meant the weapon could not be fired with its stock collapsed. When fully collapsed the weapons’ depth was just 6 inches or 15.3cm.

To Deploy:

First we unfold the stock by pushing the knurled collar forward to unhook it from the base of the magazine well. When fully unfolded a spring detent locks into the rear of the receiver.

At the same time the pistol grip also unfolds. If we had a magazine loaded into the weapon we would deploy the barrel first – in order to allow the magazine to slide back through the magazine well and fold down to lock into position. The bolt follows the barrel forward so once the magazine is locked into position the weapon has to he be charged to chamber a round.

The collapse the weapon again, first fold the stock, then depress the lever just behind the trunnion to unlock the barrel, push the barrel assembly and bolt to the rear until it locks.

The Universel’s extreme compactness was both its best and worst feature, the complexity of having every protruding part fold or retract made the weapon expensive to produce. It also gave the weapon poor ergonomics with a narrow butt, an uncomfortable pistol grip and narrow sights which weren’t ideal for quick target acquisition.

The Hotchkiss was one of a whole host of compact folding submachine guns developed after World War Two. These included the MAS MLE 1948, the MAC Mle 1947 and of course the MAT-49 from French state-arsenals. The French guns were by no means the first to have folding magazines, that concept dates back to submachine guns like the SIG MKMO. Incidentally, SIG’s last developmental iteration of their submachine guns, the MP48, was also developed in the late 1940s and retained the MKMO’s folding magazine housing.

A 2001 article from the Gazette des Armes, by Michel Malberbe, includes an account from a Legionnaire sergeant who describes using the Hotchkiss in Indochina:

“I saw for the first time the submachine gun Hotchkiss in ‘Indo’. We were responsible for the security of the RC4 [Route Coloniale 4], and the staff sent us wooden cases containing these famous submachine guns. As the documents were not very complete, our company commander… had trouble explaining how it worked. It was quite funny, because folded, this submachine gun did not look very serious. It was like a rectangular scrap metal package… We used it for the first time on the Lang Son side, during a serious collision between the Viets and a convoy… I remember that this machine worked very well. But it lacked a little precision. Anyway, it was much better than the small MAS-38 submachine gun, whose magazine always blocked [jammed] at the wrong time! On the other hand, I think I remember that the Hotchkiss did not stand up to mud and that it was misery to clean it. In addition it was quite difficult to unfold because of the buttons found everywhere. We never knew which one to press. We, in any case, always transported them in the firing position…”

While the Type Universel definitely wouldn’t win any prizes for its aesthetics, it was a ambitiously-engineered and well-built submachine gun. Despite this the design was simply too complex, as we have heard troops in the field rarely took advantage of its compact features preferring to carry the weapon at the ready. The Universel sacrificed a lot to achieve its compactness and the ergonomics of the weapon leave a lot to be desired with an extremely small butt and a hollow pistol grip that just feels wrong.

It is believed that in total just 7,000 Hotchkiss Universels were produced between 1948 and 1952. The French military rejected the Hotchkiss feeling the weapons was too complex and too expensive to manufacture. Instead, the MAT-49 submachine gun, designed by Tulle, was eventually adopted. The MAT-49 also had a folding magazine housing making it almost as compact as the Universel but without its complexities.

While it underwent some field testing with the French in Indochina no major military contracts were won but small numbers were purchased by the French police, the colonial police in Morocco and some were sold to the military of Venezuela. The Universel would be one of the last firearms produced by Hotchkiss et Cie, who had built numerous armaments for the French army during the 19th and 20th centuries, before it closed its weapons manufacturing arm in the early 1950s refocusing on automobile manufacture.

West German Police Pistols

In 1976, the West German Police issued a specification for a new small, lightweight service pistol to replace their stocks of Walther P38/P1′s and various 7.65×17mm (.32 ACP) pistols.

The police specification limited the new pistols weight to 2.2lb/35oz/1kg, it was to be no larger than 18x13x3.4cm and was to be quick to draw and safe to carry with a round in the chamber.

Earlier trials had taken place in 1974 examining pistols chambered in the 9×18mm Ultra round. Walther had submitted the PP Super and SIG-Sauer had entered the P230 for testing but with increasing criminal and terrorist activity in West Germany during the 1970s it was decided to adopt a pistol chambered in the more powerful 9×19mm round.

Mauser HSC.png

As a result a new round of trials with the new specifications was arranged. Mauser, Walther, SIG-Sauer and Heckler & Koch all submitted designs. Mauser offered the HsP,Walther offered the P5, SIG-Sauer entered the P225 (which became the P6) and Heckler & Koch submitted the PSP, later known as the P7.

The trials involved a gruelling 10,000 round endurance test (with cleaning after every 1,000 rounds), a rapid-rifle 500 round test and accuracy testing at 25 metres. One of the main problems of producing the desired sub-compact sized pistol in 9×19mm was that after approximately 1,000 rounds the pistol’s recoil spring may become prone to failure.

The police specification called for a 10,000 round lifespan. Each had their own approach; Walther’s P5 tackled the problem by using the dual-spring system used in the P38/P1 while Heckler & Koch used a gas-delayed blowback system in the P7. SIG-Sauer, however, employed the simplest solution – a heavy gauge braided spring to give increased strength combined with the Short Recoil action. This was also substantially cheaper to manufacture.

The short-recoil, lever-locked Mauser HsP was eventually dropped due to durability issues, while the Walther P5, SIG-Sauer’s P6, and Heckler & Koch’s P7 were successful and deemed fit for service and adopted by various German police departments.

The P5 was adopted by Baden-Württemberg and Rhineland-Palatinate’s State Police as well as the Dutch national police. TheP6 was the most widely adopted as it was the cheapest option available, with a total of seven German state police forces adopting it along with orders from the border police, railway police and the Federal Criminal Police Office. The most expensive of the pistols, the P7 was favoured by more specialist units like GSG9.
