WCP365 2.0 Highlights

The SIG-SAUER 365 Series is among the most reliable and safest ultra-compact 9mm pistols ever designed. Now, Wilson Combat has made it even better with a host of our proprietary custom modifications to improve handling, shooting, and optics capability. These eight new models of Wilson Combat Custom WCP365 produced in our Berryville, AR facility in conjunction with SIG-Sauer are among the ultimate in a production everyday carry gun.

The SIG SAUER P365 is an outstanding self-defense pistol, and we've reimagined it from the ground up. Customers can choose from standard, X, XL, or XMACRO Wilson Combat polymer grip modules—each developed to enhance ergonomics and recoil control. Improvements in shape, texture, and feel result in a grip that mimics a fully hand-sculpted custom firearm.

The WCP365's chromoly barrel is finished with black DLC (Diamond-Like Carbon), the most advanced PVD coating available. Chromium and tungsten under layers provide superior corrosion and abrasion resistance.

Wilson Combat engineers have redesigned the WCP365 slide with multi-pattern front and rear cocking serrations, slide top serrations, heavy slide bevels, and lightening cuts for improved manipulation under stress. In combination with a Grayguns trigger and spring modifications, we’ve refined the action to deliver a noticeably better trigger pull. Each model is available in a standard or action-tuned configuration.

The WCP365 can be ordered with an optic mounting solution or a direct-milled slide (with cover plate and rear Battlesight) compatible with Trijicon RMRcc, Holosun 407K/507K, SIG SAUER Romeo Zero, or Shield RMSc.

With improved ergonomics, enhanced shootability, and superior optics capability, the Wilson Combat WCP365 takes the P365 platform to the next level.
