SIG SAUER P320 Compact 9mm Luger Striker-Fired Pistol — Description

The SIG SAUER P320 Compact 9mm Luger is a modular striker-fired semi-automatic pistol designed to provide a balance of concealability, capacity, and full-size shooting performance. Built around SIG Sauer’s innovative P320 modular fire control unit, the pistol allows users to customize grip size, frame configuration, and caliber options while retaining the same serialized chassis.

The Compact model features a 3.9-inch barrel, compact slide, and compact grip module, making it suitable for concealed carry, duty use, training, and recreational shooting. Its ergonomic polymer frame, stainless steel slide with Nitron finish, and striker-fired operating system provide durability and consistent performance.

The P320 Compact 9mm includes a double-stack magazine system, SIG Sauer’s modular design, and an integrated accessory rail for compatible lights and accessories. Depending on configuration, it may be equipped with contrast sights, SIGLITE night sights, or other factory sight options.
