The SIG Sauer P320 is a modular semi-automatic pistol made by SIG Sauer, Inc., SIG Sauer's American branch.[7] It is a further development of the SIG Sauer P250, utilizing a striker-fired mechanism in lieu of a double action only hammer system. The P320 can be chambered in 9×19mm Parabellum, .357 SIG, .40 S&W, .45 ACP, and 10mm Auto and can be easily converted from one caliber to another; a change from .357 SIG to .40 S&W requires only a barrel change; a change from 9mm to .357 SIG or .40 S&W (or vice versa) is accomplished using a caliber exchange kit.
The P320 chambered in 9×19mm Parabellum was introduced in the North American market on 15 January 2014, followed by the .45 ACP compact model at the SHOT Show in January 2015.[8] On 19 January 2017, it was announced that a customized version of the SIG Sauer P320 had won the United States Army's XM17 Modular Handgun System competition. The full-sized model is known as the M17 and the compact carry-sized model is known as the M18.[9]
According to The Washington Post, the P320 is one of the most popular handguns in the United States.[10]
