Wilson Combat-SIG SAUER WCP320 Compact Semi-Automatic Pistol

Using the Wilson Combat SIG P320 X-Compact grip module, our in-house re-machined Compact slide, and Wilson Combat performance Battlesights, the Wilson Combat WCP320 Compact is our smallest 320 option for concealed carry and defensive use yet retains the legendary reliability this series is famous for.

This fast-handling and concealable pistol wears our Wilson Combat engineered polymer X-Compact grip module with 3-slot rail.  This updated grip has enhanced traction, smoother reloading, improved pointablity and superb recoil control in dynamic shooting.  This grip module turns an already solid platform into an ergonomic shooting machine.

The WCP320 Compact 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 Compact and gives shooters a lower finger position on the trigger which increases leverage for a lighter, smoother trigger pull.

The trigger pull can be further enhanced by Wilson Combat gunsmiths with our optional action tune using Grayguns custom trigger parts.
