The heart of this pistol is SIG’s modular, serialized fire-control unit, making caliber and grip module changes straightforward without additional transfers.
A black Nitron PVD finish protects the stainless steel slide from corrosion, while front and rear cocking serrations offer solid purchase during press checks or slide manipulations.
The striker-fired action delivers a consistent, curved trigger pull and a short reset. An ambidextrous slide stop and reversible magazine catch cater to both right- and left-handed shooters.
Steel 3-dot contrast sights provide a crisp, durable sight picture in varied lighting. An integrated accessory rail accepts lights or lasers for low-light work.
The 3-point takedown system requires no trigger pull, enhancing safety during disassembly. As the commercial counterpart to the U.S. Army’s M17/M18 program, the P320 enjoys a wide aftermarket ecosystem for holsters, grip modules, and parts.
