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.

Love the purchase on the grip

Almost perfect

First, let me say I LOVE this grip module. I removed an AXG Legion grip to use this one and I own and have tried the X grip in multiple sizes as well as the Wilson Combat and none of them present as naturally as the 1811 for me.
So why the almost, well it has nothing to do with grip mod itself. The website pictures do not do a great job of representing the color of the laser engraved grips (the laser engraving is perfect btw). Hoping for something that would match or at least not clash with a Legion gray. I looked and decided to try a gray as opposed to a boring black. The pic does not do a good job of capturing how blue the gray is. In person the combo of the blueish gray and the greenish Legion gray was punishing visually . I ended up cerakoating it immediately. The second web page vs reality issue is with the web page showing the laser engraved areas being contrasted in black compared to the cerakoat color. My gray grip module arrived mono coated in gray only. Disappointing given the cost once you add laser engraving, offset mag release and Magwell ( again, the magwell is outstanding, like hard to miss and fumble a reload outstanding.

In summary, the best P320 grip on the market for my use, fit, cost. It seems like there is some issues with selling them ( sub optimal pictures) and maybe production consistency (product not matching pictures. I want to give it 5 stars, but there are some issues.

The best grip mod

As much as its been repeated, this is THE best grip module for the P320. The laser stippling is a rough aggressive texture while remaining comfortable to hold. The ergonomics are lightyears ahead of Sig brand modules. With this grip, I can really clamp down on the pistol to ensure it doesnt move, even with smaller hands. If you are on the fence about an aftermarket P320 grip this is the only right choice.

Amazing grip and feel

These grip modules are excellent quality, comparable to the stock grips but better. I feel like I get a quicker and more consistent sight picture. Amazing customer service, I accidentally received the standard grip, they immediately fixed the issue and sent the Laser engraved etching and allowed me to keep the mistakenly sent item. Thanks guys. Appreciate you and your team.

Fast shipping, immediate customer service. Friendly responsible staff, quality products.
