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.

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

  • Enlarged, integrated magwell opening for fast reloads-compatible with the latest generation SIG-SAUER X-series factory basepads
  • Improved grip traction and increased grip pattern coverage with Wilson Combat’s exclusive Starburst grip pattern on the sides and aggressive texturing on the front and backstrap
  • Frame reference serrations for support hand thumb or index finger positioning
  • Internal Slots for Rod-style Tungsten Weights** (Click Here for Tungsten Weight Kit)
  • Angled "Holster Cuts" on light rail to aid in snag-free, re-holstering

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.
  • 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.

Great Upgrade
When purchasing my Sig M18, I was wanting a grip module that really fit well. I swapped out the the large size Sig grip module and found I had a better grip but it was not as comfortable in my hand. I found many reviews on the Wilson Combat grip module and figured I’d give it a try. The 1911 style feel and aggressive texturing on the grip really gives me a good purchase on the grip and even with bigger hands fits comfortably. The ergonomics of the grip make releasing the magazine easy without having to move my hand and the flared mag well makes reloading very easy. I would highly recommend this grip module for those who feel the stock grip module is not giving them the feeling of a good grip on their hands.
How do you advertise tan but it’s green
Feels good in my hand but the green is a total turn off I don’t know what went through your guy’s head thinking that is tan
Buy this
I had heard this module would improve the P320 firearm and decided to go for it. This module is an extraordinary improvement, in fact! Recoil management is improved, better stippling allowing for better grip, and it's a more narrow less bulky module than the one Sig provides. To me, the most important improvement is the firearm is easier to point - the angle is more conducive to the angle of my wrist allowing for faster sight-alignment. Best $65 bucks I've spent on a firearm. I hope they come out with a module for the P365 XL (my conceal carry). Thank you, Wilson Combat!
Color is OD Green, not Tan
Just got this in the mail and it is definitely not tan. It is closer to olive drab green, which is not the color I wanted. I'd rather have had black than green.
Love it
Easy and cheap upgrade to make my m18 go from blah ergos to very nice. Aggressive texture and it fits my hand so much better.
Almost perfect
I love this module. It changes the feel slightly of the M17. The stock grip wasn’t horrible really but it is slightly large. With average size hands the stock grip was a bit big especially during extended shooting sessions. The Wilson Combat grip is a bit smaller and has a ton more bite on the grip. 2 things I wish were different. One, the slots for the weights should be made to be tight so people can simply slide them in without gluing them. This would actually be easy to fix by just making the weights a bit bigger. Two, the FDE is kinda “blah”. I love the tan that Sig uses on the m17 and m18. Wish Wilson Combat did a similar color.

This is a terrific piece. Fits my hand better then any handgun grip if ever had.
Love the grip but it’s more green than tan
Got the grip on the mail today was highly disappointed with the color I actually went and seen if od green was a color they produced. I read when I bought it it would be a little darker but this is definitely way darker and I would say not tan
Sig wet the bed not making this the stock mod
Absolutely love the feel of this module! Completely changed how I feel about the M18, original just did not work for my hands. The one and only reason I didn’t give 5 stars is the mag rattle which drives me insane and darn near makes me want to go back with original
Perfect fit
Was easy to install, the fit is perfect on the gun and in my hand. Adding the tungsten weights makes a difference. Sig Sauer makes a fine handgun, Wilson Combat makes it finer.
love it but had anyone noticed a rattle?
just got my 320-cmt. fits great and feels great. just noticed when i have a clip in it, it rattles though. not sure if it just isn't a tight enough fit or what it is. clip snaps well in place and releases great but for some reason it rattles also. anyone else had this issue? or do i have a issue with just mine. ps this is being used on my p320 m18 model
Grip Mod is a HOME RUN!
This grip module from Wilson Combat turned my Sig M18 from a 'ho-hum' pistol into a 'hey, hand me some more ammo!' pistol that you just don't want to put down! Wow!!! What a difference this grip module made in the handling, feel, and performance of my pistol. Definitely a must-have.
Outstanding Improvement
The fit and feel of the grip module is a tremendous improvement over the M-17. This is a must-have for anyone who wants to improve the handling of an M17. The changeover was easy. Thanks for the product!
Typical Wilson Combat
I have the carry grip for my M18, I’m incredibly pleased with the fit and finish of the module. It gives the gun a completely upgraded comfortable feel. Just another beautifully developed product from Wilson Combat.
Just amazing
I bought this for my M17. Wow. Just wow. What an absolute difference. I’m in love with this thing. The fit in my hand is excellent. The magwell is a thing of beauty. It looks amazing and the grip texture is excellent. I want more now. If only they weren’t out of stock!!
WC320 Grip Module
Wilson Combat have done an incredible job with these grip modules. For my hand they are the most comfortable 320 grips so far. The stippling on the front and back straps is superb and gives you a firm grip that is lacking on the SIG grip. I really can't say enough good things about them.
Fits the hand so much better than the stock SIG frame/module. Installation was simple. Highly reccomended! You will not be disappointed.
