Sig Sauer P320 X-Series Grip Module Full Size Small 9mm Luger/.40 S&W/.357 SIG Coyote - Frame

The Sig Sauer P320 X-Series Grip Module is the polymer frame at the heart of Sig Sauer's modular P320 pistol platform. Molded from coyote tan polymer, this full-size X-Series module features the slightly reduced grip circumference and additional factory-applied stippling pattern that set the X-Series line apart from standard P320 grip modules. Drop in the P320 firing control unit (FCU), a slide, a barrel, and a magazine to assemble a complete P320-XFULL pistol.

This is the Small size module option in Sig Sauer's X-Series full-size grip module lineup, giving shooters the grip-to-frame fit and sight radius of a full-size P320 paired with a smaller-circumference hand fit. It mates with a 4.70" Full Size P320 slide assembly and accepts 9mm Luger, .40 S&W, and .357 SIG by way of the corresponding P320 barrel in your chosen caliber. The polymer is magwell and weight compatible, accepting aftermarket magwells and grip weight kits without modification.

The Coyote Tan finish offers a factory-correct alternative to the standard black P320 grip module, pairing well with two-tone and earth-tone slide builds for a complete, purpose-driven P320-XFULL. Use it to refresh a worn frame, change the feel of an existing P320 build, or assemble a custom carry or duty pistol from the FCU up. Slide assembly, FCU, barrel, and magazines are sold separately.
