SIG Sauer P320-M18 9mm PistolUS Marine Corps’ New Sidearm: SIG Sauer P320-M18

Firstly, after one of the most rigorous  review processes in the history of military firearms, the US Army selected the SIG Sauer P320-M17/M18 Semi-Auto Pistol under the XM17 Modular Handgun System (MHS) contract to replace the Beretta M9.

The SIG Sauer P320-M18 offers the same accuracy, durability and unmatched reliability as the M17, but in a compact size. In 2020, the US Marine Corps started fielding the M18 service pistol to replace its existing arsenal of sidearms.

In summary, the P320-M18 is a 9mm, striker-fired pistol and accepts the identical 10rd, 17rd, and 21rd magazines accepted by the M17.

Secondly, the pistol features a coyote-tan PVD coated stainless steel slide with the same optic cut as specified by the MHS contract, and black controls just like the pistols shipped to the US Army.

Thirdly, it comes equipped with a SIGLITE front night sight and removable Night Sight rear plate. Fourthly, the M18 is a P320-based platform, and has uniquely innovative modularity, uncompromising performance, and unmatched capability. Finally, the SIG Sauer P320-M18 Semi-Auto Pistol closely follows the specifications of the M18 provided to the Marine Corps.

This is now a California-Complaint Pistol!
