In 2017 the U.S. Army adopted the SIG Sauer M17 platform as their official sidearm. The decision came as a result of the most rigorous and competitive review process in the history of military firearms. Back in 2018 SIG also made a commercial variant of the P320 M17 available to the general public. Now, SIG has released an M17 X-Change Kit, for current P320 FCU owners, allowing you to build your own close replica. However, this is a limited time opportunity.

The Sig Sauer P320 M17 X-Change Kit

Like the commercial version of the M17, the P320 M17 X-Change Kit closely follows the specifications of the Army’s M17. However, the X-Change Kit utilizes the exact parts in the issued Army M17. Utilizing Army issue parts, the X-Change Kit similarly does not feature a manual safety option, like the commercial P320 M17. For this reason, it will not function with an FCU with a manual safety.

Also, a result of using Army issue parts, the slide on the P320 X-Change Kit features military issue correct markings. The slide also features a SIGLITE front night sight and removable Night Sight rear optics plate. Although it is worth noting, the only optics that will fit the slide are the Romeo1PRO and Delta Point Pro.

The P320 X-Change Kit ships with two 21-round magazines and one 17 round magazine. Albeit, with the original issue configuration, it requires high-energy ammunition to function properly. This is by design, to satisfy the needs of the military. So, this will not function well with low-energy ammunition.

The M17 X-Change Kit is only available while supplies last, so you might want to act soon. If you have a P320 FCU and have wanted an Army M17, now is the time to pull the trigger.


The SIG Sauer P320 M17 X-Change Kit is available now with an MSRP of $499.99. For more info, please visit
