The Sig 365 Series is among the most reliable and safest ultra-compact 9mm pistols ever designed. Now, Wilson Combat has taken it even further with a host of proprietary custom modifications to enhance handling, shooting, and optical capabilities. These eight new models of Wilson Combat Custom WCP365, produced in their Berryville, AR facility in conjunction with SIG-Sauer, are among the ultimate in production, everyday carry guns.
Wilson Combat WCP365 2.0- New and Improved
The Sig 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.

Redesigned Slide
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, they’ve refined the action to deliver a noticeably better trigger pull. Each model is available in a standard or action-tuned configuration.
