The full-size P320 format delivers a 4.7" barrel and a 21+1 maximum capacity with the included extended magazine. It is a striker-fired, locked-breech design with ambidextrous slide catch levers and no external manual safety. An integral 3-slot Picatinny-style accessory rail is built into the frame.
The Wilson Combat P320 Full-Size polymer grip module enhances control with aggressive texturing and an extended beavertail. The grip bears molded Wilson Combat markings, including Berryville, AR, USA, and is finished in tan to match the slide.
The slide is direct-cut for the RMR footprint and currently has a filler plate installed. Front and rear serrations provide positive manipulation, and the slide is finished in tan.
Trijicon tall night sights are installed, with a Trijicon H3 tritium front and a tall rear. Their height pairs effectively with the direct RMR cut while providing a clear, illuminated sight picture in low light.
The P320’s modular FCU system allows the fire control unit to be the serialized core of the platform. A flat-face trigger is installed for a consistent, straight-back press.
