Description
Wilson Combat engineered this grip module as a straightforward upgrade for owners of the Sig P365 family looking to refine their carry gun's feel and function. The module ships ready to drop into standard P365 pistols and comes configured without a manual safety.
What sets this grip apart is the geometry work throughout. The beavertail tang sits higher and cuts back to a 1911-style profile for smoother holster draws. The backstrap has a wider, more pronounced curve that naturally encourages a higher grip position. The trigger guard area gets undercut and reshaped to let your hand ride up closer to the bore axis, which makes a real difference in recoil management on such a compact frame.
Texture and Grip Traction on the WCP365
The surface treatment here is aggressive by design. Wilson Combat's Starburst pattern covers the sides while the front and backstrap get heavy, directional texturing meant to lock your hand in place. This isn't subtle stippling; it's meant to bite. If you run the gun wet or sweaty, or if you're working through drills fast, that texture keeps you planted without shifting. The polymer material itself takes the aggressive treatment well and holds up to extended use without wearing smooth.
What Comes in the Box
You get the grip module itself plus Wilson Combat includes the factory Sig magazine release spring and lock hardware, so installation simply means transferring your fire control unit from the original frame. The module accepts internal slots for rod-style tungsten weights if you want to experiment with recoil tuning down the line. The matte black finish resists fingerprints reasonably well and matches the look of most P365 slides.
Compatibility runs straight across standard P365 variants, and the module sits compatible with all common P365 holsters since it maintains the footprint of the factory frame.

Frequently Asked Questions
Will the WCP365 work with my standard P365 holster?
Yes, the WCP365 module maintains the footprint of the factory P365 frame, so it fits existing standard P365 holsters without any issues. If you own a custom or specialty holster, you may want to verify fit, but factory-spec holsters will work fine.
Can I add tungsten weights to this grip module?
The WCP365 has internal slots designed to accept rod-style tungsten weights, which can help manage recoil on such a compact gun. Weights are sold separately and can be installed to experiment with different balance points and how the gun feels in your hand during shooting.
What's the difference between the no-safety and manual safety versions?
This specific module comes configured without a manual thumb safety, keeping the grip profile clean and uninterrupted. If you prefer a manual safety, Wilson Combat offers a separate manual safety version. Neither affects operation or reliability; it's purely a user preference on how you want to work the gun.
Do I need a gunsmith to install the WCP365 on my P365?
Installation involves transferring your fire control unit from your original frame to the new module. While some folks handle this themselves, Wilson Combat recommends having a qualified gunsmith do the work to make sure everything seats properly and functions without issues.
