Wilson Combat
The Wilson Combat WCP320 Full Size Black Grip Module with Safety is a precision-engineered grip frame upgrade designed for SIG-SAUER P320 full-size pistols. If you're running a P320 for competition, duty, self-defense, or the range, this module gives you a custom-fit platform that feels and handles significantly better than the factory frame. Wilson Combat drew input from tactical instructors, competitive shooters, and firearms professionals to create a grip that combines practical ergonomics with the kind of attention to detail that separates a tool you tolerate from one you actually enjoy shooting.
The design centers on three core improvements: a high-cut 1911-style beavertail that allows a higher grip and smoother draw, a reshaped backstrap and undercut trigger guard that let you get your hands as high as possible on the gun, and aggressive grip texturing—Wilson Combat's exclusive Starburst pattern on the sides plus sharp texture on the front strap and backstrap—that keeps your grip consistent during recoil management. The black finish fits a wide range of carry and tactical setups. This module ships with the factory SIG magazine release, spring, and lock intact, so installation is straightforward and compatibility with your existing magazines is assured.
Important note: This grip module is not compatible with California-compliant versions of the P320, nor is it designed to work with SIG-SAUER X-Five Tungsten weights. However, it does include internal slots if you want to add optional rod-style Tungsten weights (Wilson Combat part NW734) for tuning the balance and recoil impulse to your preferences.
