M1811 Grip Mod – Deep Laser Engraved
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.

Hands down the best P320 grip module out there. The 1911 grip angle feels a lot more natural to me than the standard P320 and the shape is a lot less round and bulky. The added grip texture is superb and makes getting good purchase on the grip a breeze. The additional magwell makes reloads lightning fast. Overall this grip took my M18 from being a gun I was only ehhhhh on to one of my favorites to shoot.
Fantastic solid construction!!
My brother got one and I feel in love with it so I got my own. Love it
This is my second purchase, once again this is a great product. Great customer service with fast shipping.
The laser grip is very comfortable, the grip angle is like my 1911 who does not like that grip angle. A little on the light side, but the high beaver tail makes up the difference for the lightness . The magwell makes for easy changes.
All and All I really like this Grip. I don’t see me putting on the original tungsten grips.
