M1811 Grip Module
The Ultimate P320 Upgrade
The Brouwer M1811 Grip Module corrects the main ergonomic issues with the P320 platform – high bore axis, rounded slippery grip, short beavertail. The modern 2011 pistol is the standard for shooting performance, control, and ergonomics.
With the design of the SIG P320 series, we were able to bring some of that performance and control to polymer pistols.
Brouwer Grip Module Summary Of Improvements
Improved Handling:
The Brouwer P320 Grip Module greatly improves point of aim repeatability by utilizing ergonomics nearly identical to the 2011. The front strap angle has been changed to 107.5 degrees, with a back strap angle of 67.5 degrees to cause the pistol to seat into the hand when gripped. This geometry aids the shooter by placing the bore axis in a natural position.
The beaver tail has been moved up to reduce the height over bore while still maintaining the full functionality of the SIG P320 fire control group. The beaver tail has been profiled to draw the hand into the gun while providing a large surface to aid in reducing the effort to mitigate recoil. The rear profile of the beaver tail has been shaped to reduce catching the web of the user’s hand when gripping the gun promoting quick grip acquisition.
A large trigger guard was kept to ensure use with gloves in cold weather and reprofiled to remove unnecessary features. The profile of the trigger guard was moved up as high as possible to improve grip index relative to the beavertail while maintaining clearance for the P320 trigger. The tolerancing for the mag release button has been reduced to combat dust ingress.
Factory Compatibility
The grip module is designed to use all factory equipment that comes with a SIG P320: Fire control unit, magazine catch (reversible), slide stop, take down pin. The module accepts factory SIG P320 magazines (9mm) 17rd, and 21rd. The module is compatible with both Safety Selector equipped P320 and without. In order to work with Selector-equipped models, a small cut must be made. An interior outline has been molded into the part to assist with making the cut. We recommend a small rotary tool, such as a Dremel with a 1/8” burr bit. If this modification is not something you would like to perform, we offer it as an additional service which you can select on the store page before adding to cart.

Grip Texture
Simulated side scales similar to the 1911 are present to stiffen the grip and fill the natural void in the palm of the hand without increasing the front and back strap radii. The front and back strap have been checkered with 25 lines per inch to improve grip without damaging clothing.
Improved Magwell Design
The grip modules magwell has been profiled to ensure a loaded magazine can be inserted at up to 45 degrees out of rotation, and 20 degrees out of axial alignment with the magwell.
Proprietary Polymer Blend
The M1811 grip module is molded with a proprietary blend of polymer. A significant increase in fiber and a premium resin composite provide increased rigidity.
Magwell Extension
The grip module is capable of accepting an additional flared magwell extension should the user desire.
Accessory Rail
A MIL-STD-1913 Picatinny rail is maintained under the slide in front of the trigger guard. Note, installation of a light, or under barrel attachment adjusted for a P320 may require a universal mount adapter as the trigger guard has been improved.
Note: please use the “U” adapter plate for surefire products.
Accessory Compatibility
- The M1811 grip module is designed to fit flush with a 3.9” barrel slide. It is also fully compatible with full length slides, and shorter.
- The module is compatible with 17 and 21 round magazines. They must have the newer square peg base pads which feature beveled sides. The older round peg base pads will not work.

Textures:
Also available with deep laser engraving with cerakote options: Black, Coyote, O.D. Green, Sniper Grey. (+$120)
Very good quality grip, fits perfect in my hand and looks awesome, sadly I don’t have it together because Sig Sauer needs to fire whoever does their Cerakoting. Out the box, slide looked like it had been drawn from a holster 1,000,000 times before it was packaged. Will come back soon for a full review.
Excellent feel in the hands, and it’s exactly what I needed. The grip angle is very good. The only caveat is the texture isn’t aggressive enough. Other than that, it’s great!!!
Perfect piece of art. The grip and the texture is incredible, providing an excellent balance.
I’m a big fan of Brouwer grip module for my Sig P320. I perceive better ergonomics when I grip the pistol and with a slightly straighter mag well, it seems to point better for me. My grip was nicely finished and I took a moment to cut the thumb safety notch and save myself $20.00 for my efforts.
This was the second grip I purchased from them and it was money well spent. Now I wish they would come out with a grip for my favorite, the .45!
Great product and great customer support. I highly recommend!
I have three of these now. I own three P320 pistols and they all have the same grip module. I have tried 5-6 others and I have come right back here. Of course it’s well made, we expect that from Brouwer. But it’s comfortable in the hand, makes gripping the gun much easier and consistent…and it just looks amazing. Top tier
Excellent grip mod for the 320 exp with the magwell added. Recoil control is excellent and the natural point of aim has improved greatly. I have used the WC in the past and while it is very good this grip is better and fits my hands and shooting style even better. Thanks for a great product.
This module is a game changer! My gun actually feels right in my hand now. The best grip module I have ever bought. ⭐️⭐️⭐️⭐️⭐️I love it
Just added this module to my 320 build. IMO best module on the market. I will be saving to get the metal version for my next build. 10/10 I highly recommend.
About the M1811 grip to see what it would do to improve my P320 X Carry Specter. To say that I am happy Is an understatement. I was very happy with my gun before I put the grip module on. Now I am going to have to spend a lot more money and buy the steel grip module for it.
The grip module fits perfectly in my hand and was very easy to transfer the internals on. I have not shot with it yet, but look forward to it based on feel in hand. Fit and finish are very well done. 👍
Great fit, between the dove tail and little kicker at the end of the front of the grip I feel like it squeezes my hand in there nice and tight. And makes more real estate for my off hand to get in there in the grip. Still need to run it on range. But also did not have to change holsters. I did have to order mags since I went from a compact 15rd to this needing 17rds. But that’s the only other change I made.
The m1811 grip is a big upgrade from the stock m18 grip. I love the 1911 look and feel. Makes the 320 look so much better.
You did what SIG should've done from the beginning. I cant even look at my m18 factory grip module anymore. 10/10. Now if I could just figure out how to turn off the shake awake feature I'll have the perfect p320.
Pulling the grip module out the bag and getting a feel for it before swapping over, I could immediately tell the ergonomics of it felt way better than the stock grip module. Highly recommend making the change 🙌🏽
Great fit.The high tang makes it easy to get pressure down on you pinky. I combined this with a Romeo M17 and a MCarba trigger.
I love the feeling of a 2011 grip but I don’t have 2011 money. This grip module is awesome and worth every penny! With the added magwell my reloads are getting even better
I’d never consider myself a 1911. In fact, I’ve only ever owned one over the years, but the 1811 grip almost feels familiar to the hand. It feels as though it sucks your hand high under the beaver tail and locks it there as you draw and transition to the firing position. It’s very easy to repeat the grip as you draw. I’ll probably be buying another one soon for my other pistol. I’m anxious to see how solid it’ll feel with a bit of a silicone carbide grip treatment too. I’ve purchased and tried just about every polymer P320 grip module and size on the market, and it definitely feels the most solid. A good value and a comfortable grip.
Perfect fit and finish! Fits my hand like OJs glove.
Incredibly comfortable and if combined with a xcompact slide with a compensator you get an awesome look and usability. I embedded a little bit of tungsten/epoxy in the front of the grip module and paired it with the steel mag well and it is very balanced and light shooting.
I just received my new grip module. First impression in my hands is finally! The fit is perfect. The angle is very similar to the 45’s I cut my teeth on in the Corps. While it might be something minor, I think it is a huge plus. The outward bevel to the mag well feels so much better.
Adding a few pictures of my duty weapon (M18) with the new grip module. I took one with a 17rd mag and one with a 21rd mag. I most likely will end up buying the mag well extension. have a range day next week and will update this review then.
I’ll never go back to original grip module the m1811 feels great it makes all the difference on my m17 and m18
