Description
The Wilson Combat 365MSB brings real improvements to the P365 X-Macro platform with refined ergonomics and a texture pattern that actually works. This is a direct-fit polymer grip module designed to swap with your factory frame, making it one of the easiest upgrades you can do to enhance your carry gun.
Texture and Grip Performance
Wilson Combat's exclusive Starburst pattern covers the sides with aggressive texturing on the front and backstrap. The design gives you noticeably more purchase on the gun, which means better control during draw and shooting. Users report the textured surface feels premium without being uncomfortable against clothing. It's aggressive where it counts and appropriately textured elsewhere, which is the mark of thoughtful design rather than just slapping texture everywhere.
Ergonomic Refinements
This grip module features a high-cut 1911-style beavertail, an undercut trigger guard, and a modified backstrap shape. Together, these changes move your hand higher on the frame and let you get a more natural grip. The trigger guard undercut is particularly useful if you run a light or optic, since it lets you get higher without the guard blocking your hand. You'll notice the module feels solid in your hand from the moment you install it.
1913 Light Rail and Capacity
Unlike some compact carry pistols, the X-Macro has room for real accessories. The 1913 Picatinny rail spans 6.6 inches, so you can mount a weapon light without worrying about fitment. The module also comes with factory Sig magazine release components, so your existing setup works right away. It weighs just 2.4 ounces, keeping your carry gun light while you add capability.

Frequently Asked Questions
Is this Wilson Combat grip module compatible with standard P365 holsters?
This X-Macro version is designed for the longer P365 X-Macro platform with its 6.6-inch 1913 rail. Most modern P365 X-Macro holsters made with adjustable tension will work with it. If you're using an older holster designed for the standard P365, you'll want to verify fit since the module is specifically sized for the X-Macro. Your best bet is confirming compatibility with your holster maker before ordering.
Can I use this grip module if my P365 X-Macro has a manual safety?
No, this specific module is configured with no cuts for a manual safety. If your fire control unit includes a manual safety, you'd need to manually cut out the safety notches on both sides of the module using a hand file or rotary tool. Wilson Combat X-Macro modules have reduced thickness in the safety location to accommodate this, and there are faint witness marks to follow. This is doable but requires some work.
What makes the Starburst texture different from other grip textures?
Wilson Combat's Starburst pattern uses a radiating line design that delivers aggressive traction without the aggressive feel of some other stippling methods. The texture improves grip coverage and traction, particularly on the sides and front strap, while staying comfortable against clothing. It's intentionally designed to work for carry use, not just bench shooting.
Does this grip module work with tungsten weight inserts?
Yes, the 365M-SB includes internal slots for optional rod-style tungsten weights, which are sold separately. Adding weights forward in the grip helps with recoil management and can make the gun feel more balanced during rapid fire. Whether you use them is up to your preferences and carry setup.
