Detailed Description


The impressive modular capability of the SIG-SAUER P320 is why it has become a favorite with practical shooters and it’s thoroughly tested design will be the official US Military sidearm for many years to come. 

Wilson Combat has now reengineered the P320 grip frame to optimize its practical shooting potential.  This all new molded polymer grip module will enhance your grip and improve recoil control.  Our significant improvements in shape, texture and overall ergonomics will give your P320 the superb feel of an expertly hand sculpted custom gun with a simple grip change.

This new Carry II size grip module is a completely new size grip available for the P320 platform and combines the short, 3-notch "X-Compact / Subcompact" length dust cover with the full-size P320 grip frame for the use of a 17-round magazine.  This combination creates an ideal defensive handgun for a large-handed shooter who desires maximum magazine capacity.

Our fresh look at the P320 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 P320 grip available and the ideal choice for practical shooting or defensive handgun use.

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

The Wilson Combat SIG-SAUER P320 Polymer Grip Module features:

  • Caliber Availability - 9mm, .40 S&W, .357 SIG
  • Upgraded, high-cut 1911-style beavertail grip tang for smooth draws

P320 Grip Removal/Replacement:

  • Unload and clear your pistol.
  • Remove the slide assembly and set aside.
  • Remove the takedown lever out of the factory grip from right to left and set aside. You may need to twist/tap the takedown lever out with a non-marring tool as it is retained by a spring in the chassis.
  • Lift the chassis straight up and forward out of the stock frame.
  • Install supplied magazine catch, spring, and lock into the WCP320 Grip Module
  • Reverse the process to install the chassis into the grip frame and re-install the takedown lever.
  • You may need to tap the takedown lever in place with a non-marring tool. 
  • Reinstall the slide assembly and move the takedown lever into the locked position.
  • Ensure that your pistol functions properly and your magazine drops cleanly after installation of the new grip frame.

grip module excellent upgrade
excellent well made and built item, with ability to add weight for balance and control. highly recommended. would add to any future p320 purchase
Need to update light chart
Bought the carry ii thinking it would be compatible with my olight. Didnt end up fitting on the rail. Checked the chart and saw the streamlight tlr 1 would work. Placed the order on that and the light is so tight on the rails you cant even use the functions on the light.
Way too tight.
Installed the receiver into the module and the module was clearly out of spec. The trigger bar rubbed terribly along the module and the trigger wouldn’t reset. Hit the ejection port inside edged of the module with fine grit sand paper and run a few hundred rounds through the weapon before using it for daily carry. This seemed to bring the weapon back to factory level reliability.
Surefire X300U
Compatibility chart says that the X300U will not fit on the 3 notch Carry II. I thought it must be a mistake because I've had an X300U on my 3 notch Carry II for a couple of years. Low and behold, the chart is correct. It doesn't fit the Wilson version of this grip module. I thought it was a mistake because what does Wilson gain by changing the dimensions of the rail on this SIG Grip Module version? Maybe I've got a Wilson Grip Module that is out of spec.
How the P320 is supposed to feel
completely changes the feel of the gun. grip angle, circumference, shape and texture are different (and better) than any SIG version. points like a 1911, and i think we can all agree that the 1911 has the most natural grip angle possible. the gun shoots and points better, and conceals better. mag well has a slight flare but still conceals better than the stock modules. i'm not a big guy, i'm 5'8" on a good day, about 160lbs right now and i conceal this thing with no problem at appendix. the polymer is also better quality than sig. i have a 3.9" barrel, so the dust cover is just short enough to offer a classy look similar to the P226, which also helps with easier holstering. everyone that holds/shoots this says its even more comfortable to hold than a VP9, which (until now) was the best fitting grip i've felt. this grip is good for anyone with medium to large hands. just buy one, you won't be disappointed.
Fit for a women's hands
The other day I received my black Carry II for my P320 compact. I wanted the shorter grip as I like the visual plus it shows more of my stainless steel slide. I found the grip fits better for my smaller female hands than the original Sig grip module. After handling my pistol I quickly discovered that the backstrap and front where my fingers rest were hurting. The backstrap and front had small sharp points on them and actually cut into my skin. Yea yea yea, I know to you guys it would be fine, however my female palms are smoother than the backs of your hands. The sides were fine. Anyways I got a very fine file and WF-40 and filed down those sharp points and now all is fine.
Not for .40 cal
The details should make clear that it will not work for the .40 cal.—mags will not lock. At company’s suggestion, I trimmed the base of one of my mags, but still would not insert into the grip far enough to lock in. At least, I got a refund once I returned the grip module.
Wish they had a Compact version
I have a regular P320C (Compact) so i had to buy the 17rd mag separately, but overall i am VERY pleased with the quality of this product. It is noticeably thinner and much more “grippy” than the stock module. Processing and shipping was extremely fast too so overall a well deserved 5 stars.
Grip module
I like the way it feels and looks A lot more comfortable to carry I wish they made a compact version because I needed to buy a 17rd mag mags move in and out nice Issue iv found you need to clean off grip module off before use The slide and trigger group seems to have a tight fit the trigger bar rubs
