Selected by the U.S. military in January 2017 as the winner of the highly competitive Modular Handgun System (MHS) competition to replace the Beretta M9 series, the M17 is a variant of SIG Sauer's P320 line of striker-fired, semi-automatic pistols which utilize a serialized fire control unit (FCU) that can be readily swapped between grip frames of differing size, with the M17's FCU incorporating an bilateral thumb safety. This pistol is one of many M17s that were issued out in late 2017, with only 3,000 returned to SIG Sauer and later made available for sale on the commercial market. The included Freedom of Information Act letter from the Department of Defense states this pistol was received by 03 Infantry Battalion, Headquarters and Headquarters Company at Fort Hood, Texas, on January 07, 2018, and was later turned back in to the Fort Hood Logistics Readiness Center by 101 Aviation Battalion, Delta Company on June 24, 2019. Features illuminated night sights, optics mounting point on the slide, "+P" weight recoil spring, and Coyote PVD metal finish and polymer color. The grip unit is marked size "M" and has "19" painted in blue on the backstrap. Includes the original box dated "13-DEC-2019" identifying the pistol as "UDM17-9-SURPLUS," FDE Safariland polymer holster, 3rd Calvary Regiment patch, two extra magazines, an extra "M" marked grip unit, "M17" marked user's manual, and certificate of authenticity.
