Wilson Combat Announces WCP320 Semi-Automatic Pistol

Wilson Combat WCP320
Wilson Combat’s new WCP320 custom SIG P320 pistol.

U.S.A. -(AmmoLand.com)- Wilson Combat and SIG SAUER are pleased to announce the availability of a Wilson Combat enhanced P320 9mm semi-automatic pistol collaboration, the WCP320.

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.

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.

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 on the trigger which increases leverage for a lighter, smoother trigger pull. The pull can be further enhanced by Wilson Combat gunsmiths with our optional action tune using Grayguns custom trigger parts.

Wilson does make nice looking guns…..But in the end it’s still a $500 gun!

This is in no way a negative comment about Wilson Combat. They are amazingly talented manufacturers and gunsmiths. But as well as Sig is making the “X” series versions of the P320, I can’t see a reason to spend the money on a WC version of the P320s. I have an Xcompact and an Xfullsize, both with the flat-faced trigger and I have never been happier with a set of full sized/concealed carry pistols in my life. Oh, BTW… I’m one of those guys that carries every single day. I do cheat every once in a while though in the… Read more »
