The SIG Sauer P320 is a modular, striker-fired semi-automatic pistol introduced in 2014 by SIG Sauer, Inc. Its design uses a removable serialized fire-control unit that can be placed into different grip modules and slide configurations. The pistol became widely known after a military variant won the U.S. Army’s Modular Handgun System competition.
Design
The P320 is built around a modular fire-control unit that can be transferred between compatible grip modules and slides. This makes it unusually adaptable compared with traditional pistols that have a fixed serialized frame.
Development and release
SIG Sauer introduced the P320 in 2014 as a striker-fired handgun and a continuation of the company’s modular pistol approach. It was later expanded into a broad family of variants for concealed carry, duty use, and competition.
Military adoption
A variant of the P320 was adopted by the U.S. Army as the M17 and M18 after winning the Modular Handgun System competition. This increased the pistol’s visibility in both military and civilian markets.
Controversy and litigation
The P320 has faced controversy over reports of unintended discharges and related lawsuits. SIG Sauer has disputed claims that the pistol can fire without a trigger pull, while critics and some users have continued to raise safety concerns.
Canadian dimension
The P320 is relevant to Canadian readers as a widely discussed modern handgun platform sold internationally, including in civilian and law-enforcement markets. Canadian interest also reflects broader firearms-policy debates about handgun design, safety, and regulation.
