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.

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.

Compatible with Compact slide and 15rd Compact magazine.

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

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.

Perfect fit!
The stock frame was a hair too large for my hands.(dinky lady hands here) This frame is slightly smaller in circumference has much better ergonomics and makes my 320 feel like a whole different pistol. I love what these guys have done here!
Great Upgrade.
Great upgrade to an already great firearm. This grip module is like having a custom grip done, but for half the price it would normally cost. Good work guys!
Best Ergonomics
I have owned a P320 since the beginning. I had the original grip module, then the X Carry, briefly tried the X Compact, but the WC Module has the best ergonomics of them all, and the best stock texturing. I realize that ergonomics can be a very subjective and personal thing, so here are my reference points. The WC EDC X9 is the most Ergonomic pistol I own, with my Sig P226 with G10 grips being an extremely close second. This WC grip module makes my P320 a close third, which is saying something compared to two much more expensive all metal guns with G10 grips.
The factory Sig grip is a really good and I love it. The WC grip mod is tremendously tremendous! The next level, well done!
This grip module is absolutely amazing! If you have the original P320 grip and think it fits well in your hand, wait until you throw this on there. The feel of it is almost personal to the gun, and will make rapid fire noticeably more controllable. The only thing to watch out for is if you have the old 320 magazines you need the new 320 baseplate. Conveniently Wilson combat sells just the new baseplate for $9 instead of having to buy entirely new magazines which saved me a lot of money. Installing tip: if the FCG isn’t seating all the way into the grip module, put the slide in the grooves and push the slide back with a decent amount of force and it will seat in the grip smoothly.
