FINALLY IN STOCK – New 2025 Version!
After one of the most rigorous and highly competitive review processes in the history of military firearms, the SIG SAUER M17 was awarded the Modular Handgun System (MHS) contract for the U.S. Army. The M17 is a P320-based platform, and was selected for its uniquely innovative modularity, uncompromising performance, and unmatched capability. A compact version M18 (3.9 inch barrel) was also selected for the US Marines and some other groups of the US Armed Forces. The commercial M18 closely follows the specifications of the U.S. Army’s M17.
The SIG SAUER M18 is a 9mm, striker-fired pistol and comes with one (1) 17-round magazine and two (2) 21-round magazines, featuring a coyote-tan PVD coated stainless steel slide compatible with the ROMEO-17 red dot optic, and black controls just like the pistols currently being shipped to the U.S. Army; it comes equipped with a SIGLITE front night sight and removable Night Sight rear plate. The M18 features a coyote-tan carry-length grip module, available in three sizes, and comes standard with a manual safety.
