The P320 Compact format pairs a 3.9 inch barrel with a polymer frame featuring coarse texture panels for secure handling. It uses a striker-fired system with a curved trigger and a push-button magazine release. The slide wears a matte black finish with front and rear serrations, and the pistol is equipped with 3-dot contrast sights.
Its serialized, stainless-steel fire control unit is the core of the P320’s modularity, allowing the user to configure grip modules, slides, and calibers within the P320 family while keeping the same serialized component. The pistol is manufactured in the USA.
Magazine compatibility is broad, accepting flush and extended options. The included set covers 15-, 17-, and 21-round steel magazines, enabling capacities up to 21+1 with the extended magazine.
Safety features include an internal striker safety and a disconnect safety, with no external manual safety. The design also incorporates a takedown lever that allows disassembly without pulling the trigger.
An accessory rail with multiple Picatinny-style slots is integrated into the dustcover, supporting straightforward setup with compatible rail-mounted equipment.
