Using the all-new Wilson Combat SIG P320 grip module, our in-house re-machined slide and Wilson Combat performance battle sights, the Wilson Combat Optimized WCP320 will become the new standard in hard-use, striker-fired handguns. Our modifications have tailored and tuned the 320 platform for precision tactical pistol shooting.

Wilson Combat and Sig Sauer are pleased to announce the Wilson Combat enhanced P320 collaboration, the WCP320. This 9mm pistol includes our custom Wilson Combat P320 grip module (black or tan), P320 slide with X-TAC pattern serrations, and black DLC finish. Wilson Combat gunsmiths and engineers have completely reworked a SIG SAUER P320 chassis and unfinished SIG-manufactured slide into our ideal version of a high-performance, perfected striker-fired pistol.

This robust, fast-handling pistol wears our Wilson Combat engineered polymer grip module. This newly designed and manufactured grip has enhanced traction, smoother reloading, improved pointability, and superb recoil control in dynamic shooting. This grip turns an already solid platform into an ergonomic shooting machine.

The slide has been machined with the Wilson Combat X-TAC pattern for improved manipulation under stress. The front and rear cocking serrations, as well as the slide top, wear this signature Wilson Combat pattern. The stainless steel slide and chromoly barrel wear the most advanced black DLC (Diamond-like-Carbon) physical vapor deposition finish available. This finish has chromium and tungsten underlayers for long-lasting corrosion and abrasion resistance.

The SIG SAUER flat-faced XFULL trigger is standard on the WCP320 and gives shooters a lower finger position, increasing leverage for a lighter, smoother trigger pull. Wilson Combat gunsmiths can enhance the pull with our optional action tune using Grayguns custom trigger parts.
