The Sig Sauer P320 Grip Module X-Series in large size gives your P320 platform a factory-fresh grip assembly in rugged coyote polymer. If you're running a full-size P320 with a 4.70" slide and want to upgrade or swap to the X-Series configuration, this module is the foundation: it accepts your existing firing control unit (FCU) and pairs with P320 slides and barrels chambered in 9mm Luger, .40 S&W, or .357 Sig. Whether you're a competitive shooter dialing in your setup, a serious hunter refining your carry gun, or someone who just wants a fresh grip feel, this large-frame module delivers the ergonomics and modularity the P320 platform is known for.
Built from durable polymer in a neutral coyote finish that works equally well in the field or on the range, the grip module is straightforward to install—your FCU drops right in. Note that this module doesn't include the extended magwell or internal weight found on some X-Series variants, keeping it trim and lightweight. Also important: X-Series modules work with modern SIG Mark baseplates but are not compatible with older magazines bearing the "SIG SAUER" text on the baseplate, so check your mag setup before ordering.
This is modular shooting at its finest: swap grips, experiment with different slide/barrel combos, and tailor your P320 to your hand and your mission. The large size accommodates shooters who prefer a full-grip feel and won't sacrifice control for concealability.
