Selected by the U.S. military in January 2017 as the winner of the 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 to U.S. Army in late 2017, and later that year the U.S. Army announced the 101st and 82nd Airborne divisions were to be the first units to receive the M17, 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 The Army states this pistol was received by Alpha Company, 1st Battalion, 502nd Infantry Regiment, 101st Airborne Division (Air Assault) at Fort Campbell, Kentucky, on December 22, 2017, and was later turned back in to the Fort Campbell Logistics Readiness Center by the same Alpha Company on December 11, 2019. Features illuminated night sights, optics mounting point on the slide, "+P" weight recoil spring, and Coyote PVD metal finish with coyote colored polymer. The grip unit is marked size "M" and "11B" is written on the bottom of the magazine base in sharpie. Includes the original box dated "23-DEC-2019" identifying the pistol as "UDM17-9-SURPLUS" along with two extra magazines, an extra guide rod and action spring assembly, a "M17" marked user's manual, and an action lock.
