Dreyse Model 1907

This week’s TAB Short episode takes a concise look at the German Schmeisser-designed Dreyse 1907, my thanks to Chuck at GunLab.net for allowing me to take a look at his pistol!


The Dreyse Model 1907 was manufactured by Rheinische Metallwaaren & Maschinenfabrik (RM&M), who later became Rheinmetall. The pistol was designed by Louis Schmeisser and produced by RM&M under the Dreyse brand name.

The Model 1907 was striker-fired, blowback pocket pistol, chambered in .32 ACP / 7.65mm Browning, which fed from a 7-round single stack magazine. Introduced in 1907, but not entering meaningful production until 1908, production ceased in 1918 with approximately 250,000 manufactured.

Schmeisser filed his patent protecting the design in the US in June 1908, it was granted two years later in April 1910. Earlier German patents were filed in 1906-1907. The pistol was designed to avoid infringing on some of John Browning’s semi-automatic pistol patents. To do this Schmeisser’s pistol had a ¾ length slide which attached to a breech block.

To cock the weapon, the user grasped the slide at the front and used the slide serrations to pull it to the rear, chambering a round. Spent cases were ejected out of a port on the right side of the pistol. The pistol’s front sight was situated at the front of a scalloped trough in the slide while the rear sight consisted of a raised a notch in the upper receiver.

When fired the slide and breech block recoiled rearwards, the travel of the slide was stopped by the solid upper receiver housing. There was a frame mounted safety on the left side of the gun, with the safe position pointing to the rear. The 1907 had a heel type magazine release, typical of European pistols of the period.

The pistol’s receiver is hinged and pivots apart for cleaning, clearing and disassembly (see the original patent drawings above). There was some substantial variation, with the 1907’s design evolving during the course of its production life. Early models lacked the scalloped slide that we can see in the pictured model. Internal changes were also made with the addition of a disconnector.

The 1907 was favoured by the German police and gendamarie, with John Walter noting that most of the initial 1,000 pistol production run being purchased by Saxony’s gendamarie and later by the Berlin municipal police.  In 1910, there were abortive attempts to develop a larger 9x19mm version of the pistol. Introduced in 1911, various German state police forces and Prussia’s Border Customs officers strongly interested.

The design, however, was still an unlocked blowback and relied on an extremely strong recoil spring. The spring was so strong that it necessitated a cocking lever which disconnected the spring. This version is often referred to, but not officially marked as, the M1910. The flawed design and production problems at Rheinmetall saw the project abandoned before the outbreak of World War One.

The .32 ACP Dreyse 1907 continued to be manufactured during the war and saw service with elements of the German and Austro-Hungarian armies during, as an auxiliary side arm. The Norwegian reportedly examined the 1907 during their pistol trials (1902-1914) and found it lacking. The Czech military purchased some 1907 pistols but they were quickly removed from service and replaced with the Pistole vz. 24.
In Germany the pistols remained in police service into the 1930s, and some saw auxiliary and late-war Volkssturm service during the Second World War.

Live Fire: Hotchkiss Portative

 

The Hotchkiss Portative was one of the earliest light machine guns to see general service. It was used in action by a number of countries during the First World War, the example we’re examining today is a British Mk1 Hotchkiss Portative light machine gun.

British Portative’s were chambered in .303, and were initially issued to cavalry regiments as a light machine gun before arming some of Britain’s early tanks during World War One.

The gun was also known as the Hotchkiss Model 1909 and saw service with France, chambered in 8mm Lebel and the US, chambered in .30-06, where it was known as the 1909 Benét–Mercié Machine Rifle.

To cock the weapon the charging handle at the rear of the gun is turned to the unlocked position, at 12 o’clock, and pulled to the rear. It is then returned forward and the gun can be put in either safe, semi and full automatic.

Weighing around 25 lbs or 12kg the Portative was extremely heavy for a light machine gun. It had a small, unergonomic pistol grip to which the stock attached. This makes it difficult to hold the pistol grip and the stock attachment jabs into the hand during firing. The low position of the Hotchkiss’s stock provides a chin weld at best.

The Portative feeds from a 30-round metallic feed strip. Rounds are placed in the metallic strips and loaded into the weapon with the cartridges facing down. If not seated properly in the strip, vibration from firing can loosen the rounds causing them to fall out or induce jams. The strips were so fragile a sizer, used to realign bent or misshapen strips, was standard issue. Once the strip is empty it is thrown out of the gun with some force.

The Portative’s tripod while small and highly adjustable is poorly designed, it is unsuited to use in the field. As the gun is already top heavy and unbalanced, due to feeding from a side-loading ammunition strip, the gun has a tendency to topple over if not held firmly by the operator. This also complicates clearing jams and stopages.

We will have a full video and blog exploring the design, development and history of the Hotchkiss Portative in the future. My thanks to Chuck Kramer of Gun Lab for letting me shoot his Hotchkiss and helping with filming, check out his blog here.
