Wilson Combat-SIG SAUER WCP320 Semi-Automatic Pistol

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 battlesights, 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 pointablity 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 avaiable.  This finished 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.

I’ve always been a fan of the pistols Sig Sauer produces. They can take a serious lickin’ and keep on tickin’. But Wilson Combat has taken an already stellar Sig pistol, and refined it further. The new Wilson Combat modular frame is perfection. Super tough and fits in the hand very well, even if you have large hands such as myself. The slide is not only beautiful in its form, but its function is superb. The slide serrations will not ever snag on whatever clothing you may wear, and their design allows for superior grip when cycling the slide. The coating seems to be indestructible and will probably wear very little, if at all, no matter how many times you draw this out of a holster, or how many years you choose to carry this highly functional work of art. This gun is beautiful! The slightly flared mag well makes speedy reloading a cinch, and the Wilson Combat extended magazine catch will never let you down when securing the magazine. This gun is very well balanced and will have your shooting buddies asking if they can also give it a workout. And like every Wilson Combat handgun ever made, it is built to hammer nails all day, every day. I was so impressed with this gun, that I decided to buy a second one just to have and store away. As with every firearm that Wilson Combat produces, you can bet your life that it will function flawlessly in the event you may have to defend your life. The accuracy of the Wilson Combat P320 is second to none. On the range you will find this polymer masterpiece quite the joy to fire, and before you know it, you will have gone through several hundred rounds with ease. It is very ergonomic and shoots like guns that cost triple the price. I can go on and on about this expertly crafted polymer framed masterwork. So if you’re in the market for a full-size 9mm, I highly suggest you purchase on of these, and I assure you that your money will be well spent. The talented gunsmiths at Wilson Combat have never hit anything less than a home run. And with this beauty…they hit it right out of the park. Give this one a shot!
Almost a perfect gun
Just got to handle 2 different versions of this gun and have to say that it is the most comfortable grip and perfect texturing. Trigger in both models are amazing and I am not a sig fan so not being biased lol. The slide doesn't look like it would have grip but trust me when I say that those grooves are amazing on the slide and it is one of the easiest slides to rack. Sights are amazing and the only thing stopping me from giving 5 stars is why no optic cut? This gun with an optic would be a immediate no brainer purchase for any gun enthusiast or first time owner
