Detailed Description


*Color of Tan Module may be darker in personal than depicted in photos online*

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.

New life for a old p250
Beautiful grip looks amazing in person been going back and forth what grip to get most need trimmed as I have the subcompact slide not this one it fits perfect
I started my P320 journey with a Sig P320 X Full. While that's a great firearm it's quite large. After getting one of the Subcompact X Change kits I got the Carry 2 grip which fits the slide flush and still allows me to use 17 and 21 round magazines also flush fit. I did get an RMR optics cut along the way as well. The ergonomics are simply perfect. I did add Granulate Talon Grips grip and touchpoints but that is entirely personal preference and not required. What can I say. If you have a 3.6 or 3.9 barrel upper for a P320 you need to get this grip module.
Awesome grip replacement
I received my frame today and in 20 minutes the grip was installed. I also bought the tungsten weight kit as my 320 is chambered in Sig 357 so the added weight was an welcome addition. I then went to the range and was extremely pleased with the outcome. The grip feel is exceptional and even under some rapid fire strings in this caliber I had no problem maintaining a good purchase with this grip. I would really give this conversion some serious thought. No matter what caliber you shoot a good functional grip can enhance your shooting especially when your under stress. Don’t wait
Perfect match to SIG pro cut slide
I recently purchased the pro cut slide from SIG for my 320. After I got it, I realized I wanted something a little different for a grip module. I did not realize Wilson was making them but found them and ordered the original WC grip module. I really liked it, and then a couple of days ago, saw the newer “II” model. I ordered it with weights, put it all together today. It’s made a humdrum P320 into something special. I highly recommend it if you have gotten that pro cut slide.
