The SIG Sauer P320 is a semi-automatic pistol made by SIG Sauer of Exeter, New Hampshire and SIG Sauer of Eckernförde, Germany. The SIG Sauer P320 can be chambered in 9×19mm Parabellum, .357 SIG, .40 S&W, and .45 ACP. The P320 chambered in 9×19mm Parabellum was introduced in the North American market on January 15, 2014 followed by the .45 ACP compact model at the SHOT Show in January 2015. The P320 is a further development of the SIG Sauer P250 utilizing a striker-fired mechanism in lieu of a double action only hammer system. On January 19, 2017, it was announced that the SIG Sauer P320 had won the United States Military XM17 Modular Handgun System competition, with a specialized version to become the new M17 pistol.
Like other SIG Sauer pistols, the P320 pistol is a short recoil operated, locked breech pistol. It uses the typical SIG Sauer cam-operated barrel, which locks into the ejection port on the slide.
A key feature of the pistol is its modular design. The main module of the P320 is an internal stainless steel frame fire control unit, which consists of the integrated fire control group (trigger, and all necessary linkage and springs), ambidextrous slide release (one on each side of the pistol), ejector and four slide rails. This steel receiver unit is used in every P320 grip module, top end, and chambering combination and is inserted into the grip frame module and held in place by the axis pin of the disassembly lever. The firearm's serial number is on the fire control unit instead of the grip module. The fire control unit allows the operator to interchange differently-sized slide assembly or top end modules and polymer grip frame modules and trigger shoes and (limited) chambering conversions to adapt the gun to the individual user and address different needs.
