Switzerland Chooses the SIG Sauer P320 – Here’s Every Military Using It Now

On Thursday (4 December) Armasuisse, Switzerland’s Federal Office for Defence Procurement, announced the selection of the SIG Sauer P320 to replace the venerable P75 (SIG Sauer P220), which has been in service since 1975. So I thought it was a good time to break down all of the major militaries that have adopted the SIG Sauer P320 over the last 10 years.

The SIG P320 is a modular, striker-fired pistol that uses the typical short-recoil, tilting barrel action, with a serialised trigger group available in varying grip-frame sizes. It evolved from the hammer-fired SIG Sauer P250 and entered production in 2014.

In September 2015, the United States Army and United States Air Force released a Request for Proposals for a new service pistol. This launched the Modular Handgun System program seeking to replace the Beretta M9 which entered service in 1990. The P320 faced off against a broad field of competitors including: the Beretta APX, CZ P-07, FN FNS, Smith & Wesson M&P M2.0, Glock 17 MHS and the STI Detonics STX. Down-selection and further testing took place in 2016, before the winner was announced in January 2017. The 101st Airborne were the first unit to be issued the new MX17 and compact XM18 pistols, and fielding continued into the 2020s. The M17 and M18 have a frame mounted safety and their slides are optics ready. The USAF and US Navy procured the smaller M18, with its 3.9in barrel. The USMC also eventually selected the M18 to replace the M9, M9A1, M45A1 and M007 (Glock 19) in September 2020.

Almost 10 years after the US Army launched the Modular Handgun System program, it was announced that the MHS General Forces Configuration had been approved. The MHS GFC introduces new parts and accessories for the M17 and M18. This system allows units and soldiers to customise their sidearms to a greater degree. The new parts and accessories include new grip frames, flared magazine wells, gas pedal take-down levers, slide-mounted or stand-alone Romeo M17 Pistol Red Dot Sights and special barrels. The GFC introduces elements seen in the popular X-Carry variants.

In April 2018, the Danish armed forces became the second military to select the P320. The Danish Ministry of Defense selected the P320 X-Carry variant of the pistol. The Danish Army pistol trials began in 2017 and the P320 X-Carry beat competition from the Glock 17 Gen 5, Beretta APX and Canik TP 9 SF to replace Denmark’s P/49 (SIG P210) pistols. The Danish pistols have the enhanced X-Carry polymer grip frame, a flat trigger, an extended beaver tail, an extended removable magwell, an optics-ready slide, and a deep trigger guard undercut. The pistols do not have a frame-mounted manual safety. At the time of the adoption, Major Tom Elvius-Brisson, Chief of Weaponry Branch, Danish Defense Acquisition and Logistics Organization, said: “By far SIG SAUER’s P320 X-Carry outperformed the competition throughout our rigorous and stringent testing process… the pistol is the modern firearm we were looking for to support our soldiers. The P320 X-Carry has a larger magazine capacity, comes reflex red-dot ready for sighting, and has the ability to incorporate a suppressor – all extremely important features to our soldiers for their sidearm today.” It’s unconfirmed just how many pistols Denmark procured, likely under 10,000, and fielding of the Sig Sauer P320 was anticipated to have been completed by the end of 2019.

One of the less widely reported adoptions of the P320 came in 2019 when Mexico’s National Guard reportedly acquired 50,000 P320s. Some sources suggest that the pistol is also used by elements of the Mexican military. The pistols were procured in 2019 and appear listed in the National Guard’s 2021 Annual Activity Report. They can also be regularly seen as standard issue equipment in imagery shared by the Mexican government. Some photos of the pistols show the slides engraved with ‘SDN’ for Secretaría de la Defensa Nacional, Mexico’s defence department. The pistols otherwise appear to be stock, full-size duty model P320s in black with no manual safety present.

Canada became the next nation to select the P320, replacing their 80 year old Inglis-made Browning Hi-Powers. Opting for a full-size pistol with a 4.7in barrel, the pistol differs from the M17-pattern pistol in that it lacks a frame-mounted manual safety, and its rear sight is fixed on the slide, with the optics-mounting place located separately just ahead of it. It also has unique Canadian engravings on the slide, and both slide and frame are completely cerakoted in an FDE colour. The Canadian Armed Forces adopted the P320 as the C22, with an initial order for 7,000 pistols for the Canadian Army announced in October 2022. At the time of the announcement, Anita Anand, Minister of National Defence, said: “The Government of Canada is committed to providing the Canadian Armed Forces with the equipment they need when they need it. Replacing the Browning 9mm with the C22 full-frame modular pistol (Sig Sauer P320) will help ensure the continued operational readiness and effectiveness of all our members.” 

There is an additional option for a further 9,500 pistols to support Royal Canadian Air Force, Royal Canadian Navy and Military Police requirements. Canada’s transition to the C22 began in June 2023, when it was also confirmed that the Canadian Government was also in the process of procuring an additional 2,272 pistol and holster systems for the Canadian Army, 1,550 for the Royal Canadian Navy and 2,478 for the Royal Canadian Air Force. In December 2023, the Canadian Armed Forces also announced that they would start issuing the carry-size C24 pistol in early 2024.

At the beginning of October 2022, the Australian Department of Defence announced that under its Lethality System Project LAND 159, a raft of new small arms were selected for the Australian Defence Force’s dismounted combatants. The P320 was chosen to replace Australia’s Browning Hi-Power Mk3s. The X-Carry Pro was selected as the platform for the Sidearm Weapon System requirement. The Australian pistol has a manual safety, suppressor height sights and a 3.9” barrel. It comes mounted with a SIG Romeo 2 (half shroud) reflex sight and Foxtrot 2 white light illuminator (which itself is designated the F10). In September 2024, this package was designated the F9. Unlike the X-Carry selected by the Danish, the X-Carry Pro chosen by Australia has its rear sight mounted on the slide rather than the optics-cut plate. Elements of the ADF’s 7th Brigade became some of the first Australian units to begin training with the pistols in August 2025.

As mentioned at the start of the video, Most recently, the Swiss Army has selected the P320 X-Carry Pro to replace the P75 (SIG Sauer P220). The Swiss sought a pistol with modern ergonomics, modularity and a 30 year service life. The tender for a new pistol was launched in 2024, from the pistols submitted five were selected for evaluation and three were down-selected. After further testing the P320 beat out competition from the Glock 45 Gen 5 and Heckler & Koch’s SFP9. Intriguingly, Armasuisse, the Swiss Federal Office for Defence Procurement, noted that initially only the Glock 45 met all the mandatory criteria and was classified as suitable for service. The SIG, however, was selected following a cost-benefit analysis and Armasuisse notes that SIG Sauer are contractually obliged to resolve any issues and establish production of the pistols locally in Switzerland. The Swiss have set aside “a mid-range double-digit million amount” for the procurement of 140,000 SIG Sauer P320s, with the initial lot numbering 50,000 pistols. The image shared by the Swiss Army showed an FDE pistol while a subsequent photo shared by SIG Sauer Switzerland showed one with a black slide and a green frame with a Swiss Cross on the grip.

Despite controversies surrounding the pistol, and SIG Sauer’s ongoing response, the P320 continues to win major military contracts around the world. SIG have optimised their approach: partnering on a number of occasions with credible local companies and offering a capable but, perhaps most importantly, affordable sidearm, as such at the time of writing the P320 is involved in a number of ongoing and upcoming pistol trials.

Colt Canada / Diemaco C7 Rifles & C8 Carbines in Ukraine

We’ve seen a large number of different small arms being transferred to Ukraine. The large number of different 5.56x45mm chambered rifles is especially interesting. This is the first of a series of videos examining the variety of different 5.56x45mm rifles which have been seen in the field. These range from US M4A1s to FN F2000s and everything in between. 

We’re starting the series examining the use of Colt Canada produced rifles and carbines. We first began to see Colt Canada C7 rifles appearing in the hands of Ukrainian personnel in May. They have continued to be seen in use with units including the Belarusian Kalinouski Regiment, International Legion Units and most recently one was seen in the hands of Ukrainian special operations forces landing on the Kinburn Spit.

Diemaco, renamed Colt Canada in 2005, began producing the C7 in 1982. These were derived from the US M16A1E1 programme which led to the development and adoption of the M16A2. The C7 differs from the M16A2 in a number of ways but principally in that it retains the M16A1’s rear sight set up and its semi- and full-automatic fire modes, rather than the A2’s 3-round burst. The versions seen in use in Ukraine are C7A1s, which replace the fixed carrying handle with a modified Weaver rail for mounting optics.

The primary users of the C7A1 are Canada (who have since moved to the C7A2 and C8A3), Denmark who issue the C7A1 as the M/95 and the Netherlands who adopted the C7A1 in the early 1990s. All of the countries also use the C8 carbine with the improved Integrated Upper Receiver. The Netherlands field the C8 as the C8NLD and the Danish Army uses it as the M/10. the United Kingdom currently fields the C8 SFW as the L119, and may have other earlier variants of the carbine in inventory.

I reached out to the Dutch, Canadian and Danish defence ministries and while the Dutch and Danish ministries declined to comment the Canadian Ministry of National Defence responded to confirm that Canada has not, to-date, provided any C7 pattern rifles. Instead, the Canadian spokesperson confirmed that Canada has provided an unspecified number of C8 carbines. 

Another indicator of this is that some of the photographs show the original Diemaco stylised ‘D’ roll mark on the magazine housing. Canadian C7A1s have the ‘D’ roll mark above the trigger, with a Canadian maple leaf engraving on the magazine housing. Sources state that Colt Canada refitted most of Canada’s C7A1s into the C7A2 configuration, with a collapsing buttstock, in the 2010s. The available imagery isn’t clear enough to make out smaller national markings to differentiate where they originated from.

This means that the C7A1 rifles seen in Ukraine were likely provided by either the Netherlands or Denmark. The Netherlands adopted the C7A1 and fielded it with ELCAN SpecterOS3.4x (C79). Interestingly, there has also been at least two sightings of a 6x ELCAN Hi-Mag on a C7A1 in early October. The Hi-Mag was adopted by the Dutch military as a machine gun optic which may point to at least some of the rifles coming from a transfer from the Netherlands. I have not been able to find any mention of the Danish armed forces using the Hi-Mag. [Update: on further research and discussion with Dutch sources the C7 pattern rifles have now been confirmed to be of Dutch origins. The key identifying characteristic being the small QR code tags seen on the right side of the magazine housing. We will have a more detailed article on this in the future.]

The C7A1s have been seen fitted with a mix of ELCAN C79s, Aimpoint Comps, various reflex sights and some with original Diemaco/Colt Canada rear iron sights. Some have already been adapted with some pretty interesting paint schemes and fitted with suppressors.

It is also unclesr where the C8 carnines seen in Ukraine originated from. While the Canadian Ministry of National Defence confirmed C8s had been sent to Ukraine, an anonymous source close to the programme to transfer the weapons noted that the carbines sent were in the C8 SFW configurations with a railed forend. The C8s seen in the field, with the earlier non-railed handguards, may be from Denmark or the Netherlands.

The first appearances of C8s in videos shared to social media that I could find date to September, but they’ve likely been in use prior to this. This piece of combat footage which was shared on social media around the 19 September is especially interesting as we see C8 carbines with ELCAN Specters but at least one has a red dot and magnifier set up. We can also see TRIAD rail mounts which are attached around the front sight base. This may indicate the carbines are C8A3s but its difficult to make out the other defining features of the A3. The TRIAD was developed to allow attachment of accessories without changing out the hangdguards, in this case most of the guys appear to have fitted vertical front grips.

An individual on the Kherson front has also shared numerous images and videos featuring his personal weapon – a C8 with a suppressor and what appears to be a more modern ELCAN Specter. The individual also shared some footage of himself and others running a contact drills.

It also appears to have a vertical front grip just visible, attached to a Triad rail mount under the front sight post.

Another photo of the operators from the 73rd Naval Special Purpose Center may be the first image of a C8 SFW – the carbine appears to have a railed forend with a laser/light module fitted along with a vertical front grip.

In future articles/videos we will explore the plethora a 5.56×45mm chambered rifles, carbines and light machine guns transferred to Ukraine.

Thank you to War_noir on twitter and StreakingDelilah on Instagram for sharing several additional photos of C8s.

Update – 01/12/22: Ukrainian SSO have shared a video with an operator discussing recent operations which gives a good look at his C8 carbine.

Update – 30/01/23: The Belarusian Kalinouski Regiment, serving with the Ukrainian Armed Forces, has shared a photo of a Dutch Diemaco C7A1. Note the C79 ELCAN and original Thermold magazine which were shipped with the guns. The armory QR code tag can be seen on the magazine housing – identifying this rifle as of Dutch origins.

Update – 15/02/23: Another recent photograph showing a Dutch C7A1 rifle with an ELCAN Hi-Mag optic, originally used on Dutch light machine guns.

Update – 26/02/23: Elements of the Azov Brigade have been equipped with Dutch C7A1 rifles (and ELCANs). Azov released these training photos a couple of days ago, on 21 February.

Update – 12/05/23: Ukraine’s SBU shared photographs showing personnel armed with C7A1s

Update – 17/05/23: Some recent examples of stock C7A1s being adapted with aftermarket furniture to increase the rifle’s modularity.
