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. The commercial M17 closely follows the specifications of the U.S. Army's M17. The SIG SAUER M17 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 M17 features a coyote-tan carry-length grip module, available in three sizes, and comes standard with or without a manual safety. This firearm is equipped with a manual safety. A manual safety - when engaged - is designed to mechanically prevent the firearm from discharging when the trigger is pressed, either intentionally or unintentionally. You should consider whether a manual safety on a handgun is right for you based on your experience level and intended use, keeping in mind best practices for safe firearms handling. It is possible for the trigger to be unintentionally pressed even under normal handling circumstances.
