Detailed Description


Wilson Combat has reengineered the SIG-SAUER P365/P365XL grip frame to optimize its practical shooting and concealed carry potential.  These all-new molded polymer grip modules will enhance your grip and improve recoil control.  Our significant improvements in shape, texture, and overall ergonomics will give your P365 the superb feel of an expertly hand sculpted custom gun with a simple grip change. These six new models cover standard and XL P365 frames, with or without a manual safety in black and tan color.

Our fresh look at the P365 grip module incorporates the suggestions of tactical trainers, champion shooters, and firearms experts into the final product that has a look that is unmistakably “Wilson”.  We believe it is the most practical, comfortable, and stylish P365 grip available and the ideal choice for concealed carry and defensive handgun use.

These are non-serialized, newly manufactured grip modules and are not serial numbered firearms.

P365 Grip Removal/Replacement:

  • Unload and clear your pistol.
  • Remove the slide assembly and set it aside.  Keep your takedown lever in the down position.
  • Remove the rear frame pin from left to right with a small punch.
  • Lift the chassis straight up from the rear at a forward angle out of the stock frame.
  • Install supplied magazine catch, spring, and lock into the WCP365 Grip Module
  • Reverse the process to install the chassis in to the new grip frame.
  • After installation, ensure that the takedown lever is under spring tension and the slide safety lever isn’t blocking the slide, reinstall the slide assembly and move the takedown lever into the locked position.  Ensure that the slide lock and takedown lever have spring tension.
  • Ensure that your pistol functions properly and your magazine drops cleanly after installation of the new grip frame prior to use.

This simple mod brought my NRA XL from excellent to outstanding! Just enough flare in the grip to nest the pistol securely in the hand. Only glitchy part was the cursed mag release installation and even that was painless. Good Job Wilson!! Kudos!!
I put one on my std. 365 about 2 months ago and it exceeded my expectations. Just purchased a P365 XL Spectre Comp, even with their custom shop module it didn't feel as good as my std so now it also has one of your modules on it, just installed this morning. Can't wait to shoot it!
Definitely worth it!
This was a great upgrade for my P365XL. Highly added recoil control with this aggressive grip stippling. VERY easy to install, and worth every penny.
I love this grip.
I bought this to improve the stock grip (I have big hands) and this gave me another 3/16 more gap for my support hand. I tried a Hoag rubber grip over it and It improved it even more. This combo just made my 365XL my main carry again, Thanks Wilson. Just waiting for the weights to complete the system.
Awesome so far
Just received this in so I have not fired it yet. That said so far I love it. This grip mod make my 365xl feel like a full size without compromising concealment. Just feels and look great.
Excellent Tactile Register
This grip module kicks @ss. It feels like it was designed for my hand, specifically and I have sub average size hands. I like the aggressive texture and placement. It feels like if it were wet and muddy or oily I could still keep a good hold on it. The quality of the frame is very good polymer. One thing I noticed is that if you hold the frame up to the light and look up the mag well toward the trigger you can see light coming through where the plastic gets thin around the trigger undercut. However, please note that it is uniform on both sides and it feels very solid and strong on those spots. pressing on those spots solidly with my thumbs and it did not feel and any less solid to me. If there is a weak spot at all, it would be there but I dont believe it to be a structural concern. It was designed that way obviously to maximize the trigger undercut and it feels great. The swell is fuller in the palm and the under cuts give me a more solid purchase. The color is like a slightly golden and a shade darker fde/sand color and it looks really sharp with the black hardware. Also, the older 365 12 rnd mags fit in the Wilson if you simply take off the skirts and put the baseplate back on. Boom! They do Not fit in the Sig P365 X series grip modules without some construction or buying more baseplates from sig. Thank you Wilson! I wouldn't mind trying the tungsten rods out and will order them when they become available for sub $20. I am really happy with this Wilson grip module, as it is a major upgrade for a just a few bucks. The grip module feels excellent to me and gives me a superior tactile register, whilst procuring a solid purchase on it. 😁
