Compatibility: Sig Sauer P320 9mm / 357 sig / 40

The M1811 Grip Module is compatible with SIG P320 models equipped with and without the Safety Selector. All modules ship without the cutout for the Safety Selector, however, a recess has been added inside the module to assist in guiding the cutout. A rotary tool with a 1/8″ burr bit is preferred. See our product details page for more info.

If you would like Brouwer LLC to perform the Safety Selector cut out for you, please select it from the drop-down below, and allow 2-3 additional days for processing.

The Brouwer M1811 grip module corrects the main ergonomic issues with the p320 platform – high bore axis, rounded slippery grip, short beavertail. The modern M1911 pistol is the standard for shooting performance, control, and ergonomics. The overall grip shape, feel, and design of the modern 1911 has not been replicated until now. With the design of the SIG P320 series, we were able to bring some of that performance and control to polymer pistols.

    Amazing adaptation between 1911’s and the sig p320, my wife loves it as her first race platform. Only points I noticed is the mag well could use a bit for blending and for my larger hands can’t get a full grip because of the mag well.

    Better than stock grip but…

    It’s too slick and needs more traction.

    I’m not a fan of the design trying to mimic the side grip panels of a 1911.

    The bottom rear of the grip could use some help.

    The mag well, grip angle, undercut, tang are all superior and make the 320 better.

    The grip is going to appeal to 1911 fans. But some of us dont really like some aspects of 1911 design.

    I have to give them huge credit for their customer service and support. Not many companies can even come close to the level of support that was provided.

    Very comfortable, and gives a whole new feeling to the P320. Grippy, but not aggressive. If I had a complaint, it would be that the beavertail is too oversized; should be more like a X-frame in that regard. Also, for the price, I’d think it could come with an installed mag release.

    I do look forward to getting a second module soon.

    Honestly love this grip mod. Ergos on it are fantastic. Maybe it’s the placebo effect but it really feels like it brings the bore axis down closer to your hands, compared to Sig’s and other third party grip mods, taming recoil and muzzle flip.

    My only real gripe is the thickness of the front of the trigger guard which disallows use of most of the standard light rail interface keys, particularly with the x300, requiring you to use a universal key which leads to sloppy lock up on the rail. Easy enough to take a few hundredths of an inch off with a dremel but I feel like this could be very easily rectified by Brouwer in the design without compromising the integrity of the trigger guard.

    Adding channels to add Tungsten weights similar to the Wilson Combat grip mod would be appreciated too. Maybe on the gen 2.

    Fantastic module that goes above and beyond in fixing ergonomic issues I have with the P320. Excellent quality and absolutely no issues from Brouwer, however it would be nice if they had an option to include a OEM mag catch. It should also be noted that the grip itself can get pretty slippery in cold or wet environments, so I would definitely recommend getting some grip tape to beef it up.

    Unfortunately, as much as this is a significant improvement over the stock or even XFive module, it wasn’t enough to convince me to keep my P320. Hats off to Brouwer though, if you like your P320 and want to make it feel better to shoot, this is an excellent option.
