Description
Wilson Combat has completely reworked the standard P320 grip module with one goal in mind: making a pistol that's genuinely more comfortable and controllable to shoot. This grey polymer frame replaces your factory grip with something that feels like a custom handgun right out of the box.
Ergonomics That Actually Work
What sets this module apart from basic grip swaps is the attention to detail in how it fits your hand. The high-cut 1911-style beavertail sits naturally against your palm without the dead space of standard frames. The undercut front strap lets you ride your thumb higher on the frame, which translates to better control and faster sight alignment. The reshaped trigger guard is also radiused instead of sharp, making your grip more secure without the pinching you get from some aftermarket options. Real shooters notice these things immediately.
Texture and Control You Can Feel
Wilson Combat's exclusive Starburst grip pattern covers the sides with raised texture that grips your hand without being overly aggressive. The front and backstrap feature tighter texturing that works whether your hands are dry or sweaty. Unlike some grip modules that feel like sandpaper, this strikes the right balance between control and comfort during extended range sessions.
Smart Features Built In
The module comes with an enlarged magwell opening that's compatible with current SIG X-series factory basepads, making reloads faster and smoother. Three internal slots let you add optional rod-style tungsten weights if you want to adjust the gun's balance and reduce felt recoil. The light rail includes angled holster cuts to help your gun sit cleanly in a holster without catching edges. Factory SIG magazine release components are included so you can keep your original grip module as a backup.

Frequently Asked Questions
Is the Wilson Combat grip module a drop-in replacement for my P320?
Yes, installation is straightforward and doesn't require modifications to your pistol. You'll remove the takedown lever from your factory grip, lift out the chassis, and install it into the Wilson Combat module. Most shooters complete this in a few minutes without any gunsmith work.
Will this grey grip module fit my current P320 slide and magazines?
It's designed for full-size P320s with 9mm, .40 S&W, or .357 SIG calibers and works with current SIG X-series factory magazines and basepads. If you have older magazines with the round peg basepad instead of the square peg, you'll need to modify the basepads or upgrade to newer ones.
Can I add tungsten weights to this grip module?
Yes, three internal slots are built into the module to accept optional rod-style tungsten weights (sold separately). Adding weights helps balance the gun and can reduce felt recoil, which some shooters find improves control during rapid fire or dynamic shooting.
How does the Wilson Combat grip compare to other aftermarket P320 grip modules?
The design philosophy is different from metal-frame options or budget polymer alternatives. Wilson Combat focused on hand-filling ergonomics, refined texturing that grips without being aggressive, and practical features like the magwell and weight slots. Most shooters who've tried multiple modules report that this one simply feels better in their hand.
