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

The Wilson Combat WCP320 grip module is a purpose-built replacement frame for your Sig P320 Carry II, engineered to transform how the gun feels and shoots in your hand. This polymer grip module comes configured for no manual safety—ideal if you're running a streamlined carry gun or competition setup—and chambers 9mm, .357 Sig, or .40 S&W. Wilson Combat designed this piece working directly with tactical trainers and competitive shooters, so the ergonomics, texture, and proportions reflect real-world feedback from people who use pistols hard.

The grip geometry here is thoughtfully different from stock. You get a high-cut 1911-style beavertail to support a smooth draw and full web grip, a reshaped backstrap that points naturally, and an undercut front strap paired with a radiused trigger guard—all aimed at getting your hand as high on the gun as possible. That matters for recoil control and repeatability. The grip panel itself features Wilson Combat's Starburst texture on the sides and aggressive texturing front and back, so the gun stays put even when conditions or your hands are less than ideal. The module also accepts optional rod-style Tungsten weights if you want to fine-tune balance or manage recoil characteristics further.

Installation is straightforward—you'll retain your factory Sig magazine release and spring. One important note: these modules are not compatible with California-specific P320 versions, so verify your gun's origin before ordering. This is a genuine upgrade path for shooters who want a P320 that handles better, locks in more securely, and matches the customization standard Wilson Combat is known for.
