The P320 FULL-SIZE is a complete, serialized pistol ready for immediate use. It’s designed for shooters who want a duty-sized platform with the modularity to change grip modules and calibers down the line. Since adding it to our lineup in summer 2025, this has become a consistent reorder item for us, moving over 68 units to date. Its popularity stems from its out-of-the-box reliability and straightforward design.
Stand-Out Features
