M1823Grip Module - Steel- 3.9in
M1823-(3.9”)
Long overdue! Our flagship M1811 is now available in steel, with all the features of the full-size steel grip Including our proprietary aggressive texture, round trigger guard, and generous beaver tail. This little brick weighs in at 1lb 7oz and provides recoil mitigation second to none of its class. For anyone looking to pair there favorite comped shorty slide and truly eliminate the snappy feel of a short pistol this is the solution, and while maintaining a manageable form factor. We understand the importance of keeping the weight where is should be, under bore centerline in your grip. A shorter correctly weighted pistol can also minimize tendency’s to over drive in transitions as well as reduce sight movement, that is sometimes experienced with a longer slide models that produce more mass traveling over center.
“Bottom line is it makes a compact a bad ass little brick that your buddies ain’t got!”

M1823Grip Module - Steel- 3.9in


The Ultimate P320 Upgrade
The Brouwer M1823 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. Be sure to order the correct version!

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.
Both the front and back straps feature meticulously machined, aggressive grip patterns, ensuring a rock-solid, reliable grip even in the harshest shooting environments.
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.
