In January 2017 it was announced that SIG Sauer had won the highly competitive U.S. Military Modular Handgun System (MHS) contract to replace the Beretta M9 as the standard U.S. military sidearm, 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. Only 3,000 of these pistols were returned to SIG Sauer for sale on the commercial market. The M17 is a variant of the SIG Sauer 320 modular pistol and integrates an ambidextrous thumb safety to the modular fire control unit. Features illuminated night sights, optics mounting point on the slide, "+P" weight recoil spring, and coyote tan metal and polymer finish. A sticker numbering the pistol "9" is adhered to the bottom of the frame ahead of the trigger guard. The grip unit is marked size "M." The shipping box is a numbered match to the pistol and identifies it as "UDM17-9-SURPLUS" and contains two extra magazines, a standard weight recoil spring, cable lock, and papers. An included Freedom of Information Act letter from the Department of Defense states this pistol was received by B Co., 96th Aviation Support Battalion, 101st Airborne Division in Fort Campbell, Kentucky, on December 18, 2017. On May 6, 2019, the pistol was turned in to the United States Army Tank Automotive and Armaments Command in Warren, Michigan.
