SIG SAUER P320 M17 Manual Safety Massachusetts Compliant – 9mm, 4.7″ Barrel, Coyote Tan, 10-Round
The SIG SAUER P320 M17 Manual Safety Massachusetts Compliant is the civilian version of the U.S. Army’s Modular Handgun System (MHS) pistol, offering the same full-size configuration, modular design, and military-inspired features in a Massachusetts-compliant package. Chambered in 9mm Luger, the M17 features a 4.7-inch barrel, a striker-fired operating system, and an integrated manual safety for an additional level of user-controlled security. (Sig Sauer)
Designed for durability and adaptability, the P320 M17 features a coyote tan PVD-coated stainless steel slide, a full-size carry-length grip module, and a serialized fire control unit (FCU) that allows the grip module and other components to be configured to suit individual preferences. The pistol includes high-contrast sights, an optics-ready slide cut, and an integrated MIL-STD-1913 accessory rail for compatible lights and accessories. (Sig Sauer)
This Massachusetts-compliant configuration includes 10-round magazines while retaining the M17’s full-size ergonomics, ambidextrous controls, and modular platform advantages. The P320 M17 has been selected by multiple U.S. military branches as the M17/M18 service pistol platform and remains one of SIG SAUER’s most recognized handgun designs. (Sig Sauer)
