Wilson Combat WCP320 Grip Module for Sig P320 Carry - 9mm, .357 Sig, .40 S&W, Manual Safety, Polymer

The Wilson Combat WCP320 grip module for Sig P320 Carry is a purpose-built frame upgrade that transforms how your carry gun feels in hand. Whether you're running your P320 at the range, in competition, or for everyday defense, this polymer grip redesigns ergonomics, controls recoil, and brings a custom-quality fit to a factory platform. Wilson Combat engineered this module with input from tactical trainers and competitive shooters—visible in every detail from the high-cut beavertail to the aggressive texturing that anchors your grip when it matters.

The geometry here sets it apart from generic grip upgrades. The modified backstrap promotes natural pointing and a higher grip purchase, while undercut front-strap and reshaped trigger guard let you get your hand further forward—critical for recoil management and shot placement in a defensive context. The Starburst pattern on the sides and aggressive texturing on the frontstrap and backstrap deliver the traction you need without feeling abrasive during extended shooting sessions. Wilson Combat includes the factory SIG magazine release, spring, and lock, so installation is straightforward; the module also accepts optional rod-style Tungsten weights if you want to dial in the balance to your preference.

Available in black with a manual safety, this grip module fits 9mm, .357 Sig, and .40 S&W Carry-frame P320s. It's compatible with standard holsters and suitable for practice, competition, self-defense, and tactical use. Note: not compatible with California-compliant P320 versions or X-Five Tungsten weights.
