Brouwer Solutions


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.

    Excellent Grip Module; one of the best for the P320 in my opinion. Tight FCU fit, excellent quality, and excellent ergos. Also fits all my P320 holsters. If you want to go another step up beyond the Wilson grip module, like the 1911/2011 grip angle, and/or have larger hands, I cannot recommend this enough.

    The grip module looks and feels amazing. The best costumer service I’ve ever had, answered my questions very quickly and was very understandable, will definitely be buying more products in the future.

    The turnaround time was pretty slow, I was communicated with but It took a few weeks to get to me. The other thing is that my surefire x300 light didnt fit.. so I had to scrape off some of the polymer to make the picatinny fit. Not sure if that was supposed to be that way but it was a pain.

    The M1811 fits much better in my hand than any of the other modules I’ve tried. I did have to trim down some of the baseplates on my older mags to fit, but it was no big deal.

    Awesome grip, with P320 extended mags they will need to be trimmed to be able to fit but that’s no big deal and an easy fix, fits perfect in my alien gear tan tactical holster and the shipping and any questions I had got answered extremely fast!

    This grip module is without a doubt the most comfortable and ergonomic option for the Sig Sauer P320 that I have used to date, and I own quite a few from Wilson Combat, Polymer 80, Sig AXG, stock Sig X-Series, customized Sig X-Series. I really hope that Brouwer makes a Compact version in the future to fit 15rd mags.

    I’ve tried every other P320 grip module out there, and this is the one I’ve been hoping for. This is a real- deal 1911 grip feel. The angle, shape, and front and back strap checkering are all spot on. Brouwer absolutely got it right with this one. Thank you.

    This thing…this thing is where it’s at. I have tried most Sig P320 Grip Modules on the market, put lots of rounds through them, and none of them come close to the M1811. So I do have a small spot in my heart where 1911’s hangout and like to remind me that even though I won’t carry them again, that they still are pure American sexy. Well, I have a few 320’s that I carry majority of the time now, one of them being an M17 with the Safety deleted, TLR-1HL, and rocking a flat faced trigger. I always wanted a 1911 to be a bit lighter to carry, and hold more rounds and what better way to do that, then to get one of these modules! Sure enough, as soon as I get it, took it to the range for a few hundred rounds of a burn down and accuracy test to make sure she functions properly. At the end of that range session, I came to the conclusion that this is the only Grip Module I will run on my M17, and it will be my main carry because of it. I do carry AIWB and the grip is nice and thin (but like a good 1911 it still fills the hand) and doesn’t print at all. For anyone looking to get a Light-Bearing AIWB holster that will fit that combo, Eclipse Holsters’ Siruis will work just fine. The grip module is great homie’s thanks!

    This grip fixes many of the problems with the P320 platform. The grip angle is comfortable and was very easy to swap out. The manual safety cut was perfectly done.

    This is probably one of the best aftermarket grips you can get for an Sig P320. It feels great in the hand and the material it’s made from is perfect for custom stippling.

    This is a great grip. So comfortable and as a 1911 shooter very familiar. The p320 grip is a bit to vertical for me. Wish you had more colors though. Maybe a light grey.

    It was just amazing. The fit was perfect and the grip angle made everything just work. It helped with the dot acquisition. Since i have a X-compact slide, i cut the excess grip and it worked out perfectly. Thanks to Matthew for all his help and answering all my questions which I’m sure he gets fifty times a day. Perfect product. I’m getting the black one next.

    Very well made and easy to install. A little slick but that was easily fixed with some grip tape. Looking forward to the magwells being available!

    Arguably the better grip module on the market right. The 1911 grip angle makes the P320 a whole new gun.

    It’s fantastic. Do it now. Why are you still reading this? Did you buy it? Buy it. Now. I got one without the extra grippy stuff in it and dropped in my mag release and it’s…yûss. It’s what the M18 shoulda been from the factory. Bröthêrs, it’s worth the money.

    Overall the finish is nice. Would have liked it to be tackier or a more aggressive grip texture from the factory but I see now they have the option to w hence the grip texture. It definitely feels good in the hand and points very naturally. Installation was a breeze but that’s to be expected. My only concern is that there is something off in the tolerances around the FCU and there is something causing the trigger to bind up and the grip module does not let the trigger reset properly. I’m going to have to heat it up or carefully smooth out the inside to allow for free movement of the trigger bar. Once that’s accomplished I will be extremely pleased with the grip. Good price point too.

    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.

    Excellent grip module for the price! The M1811 module provides great purchase area for the off hand to get a proper grip when shooting. The slim profile of the grip allows for greater control when shooting with a single hand. Just wish the grip had the option for carbide coating before I bought it.

    Love these modules and with now having the option for a more aggressive grip texture in the Silicone Carbide, I personally think these are one of the best modules available. Thank you!

    This grip is amazing, it completely changes the feel of my p320. I have the m18, x grip, tungsten infused, and Wilson combat grip modules and this is by far the absolute best one. The only criticism I have, and it is extremely minor, is I with the texture on the sides was as aggressive as the front and back. However, it is thick enough that you could send it off to be stippled. 100% would recommend.

    I have carried a 1911 for several years before switching to the 320 with a red dot. Every time I dry fire practiced, my dot always presented a few inches high at about 10 feet. When I switched the grip out, it presented like my trusty 1911, spot on.
    At the range, on target time is greatly reduced and follow up shots are noticeably quicker.
    This grip is a must for anyone who cut their teeth on a 1911 and decided to have a more modern weapon system.
    I just wish Sig would have thought about it when they built the gun, since they didn’t, I am glad Brouwer did!

    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.

    I would give this product a 100 out of 5 if I could. Handling feels great, waiting for the magwell extension to drop but this is the best grip/frame for a 320 I’ve ever dealt with!

    This grip module for the 320 is amazing. It’s comfortable, fits well in most hand types (I’ve let a lot of people try it out), and it’s still gripable in the rain. I use it for duty, and not only can I use this for a more tactical look, it looks really good in a Class A 80’s style throw back uniform. I would recommend this for anyone looking for an affordable grip module to an already good handgun.

    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.

    My opinion and preference for the P320/M17/M18 completely changed for the better with this grip. My hand is on the small side of medium and the pistol now fits very much like a 1911. The SIG X-grip was better than stock, but not as nice as the Brouwer.

    With a trigger job and Apex trigger bar it now breaks at a clean, crisp 4.25 pounds — no more “Staple gun” break.

    The 1811 grip and trigger job make this a VERY worthy (and much more reasonably-priced) competitor to the Staccato and Prodigy — from someone who has carried a Government Model for almost 50 years.

    My son set up his Camp Perry M17 with a Brouwer grip with the new textured surfaces (photo is original grip before texture):

    This product is awesome. The 320 is a great platform but the factory grips feel like you are holding a potatoe. This solves that and makes the 320 really come into its own

    Perfect upgrade for a P320. I have no desire to try another frame after getting this one. The feel and shape is perfect. Still works with my stock P320 kydex holster. Just had to tighten a couple screws and it fits snug and secure.

    Overall improved grip, not a fan of how slick the grip feels, some texturing would’ve been idea to really sucker down that grip. But this is by far one the best modules to have come out for this platform. I can’t wait to see what they do next.

    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.

    Won a P320 M18 in a raffle draw, I had shot one before and was “meh” I’ve been a 1911 and a 2011 guy lately and I saw this grip module and ordered it. And wow, it’s changed the whole dynamic of this platform for me. Fit and finish is top notch, color is as close to perfect as the factory as possible. The overall aesthetic is nice. I had a little trouble with my mag release and it being a little stiff but it will wear in I’m sure. Y’all definitely have an awesome product with this one. I’m telling anyone that has a 320 to check it out. Well done 👍🏻

    The M1811 Grip Module is a solid and well crafted alternative for the stock Sig grip module. The 1911 style grip angle points very naturally and offers some decent checking front and back of the grip. The coyote coloring matches the M18 very well and I’m looking forward to shooting it more. I do have a couple things I would have liked to see, and hope may be integrated into a v2.

    Firstly, as this could be a great replacement or the M18 and an option that could be marketed to military units, I wish the grip checkering and grip and the side panels was just slightly more aggressive to assist in gripping the gun with wet, dirty, or gloved hands. Next, I would like to see the ability to utilize the grip weights from either the TXG module or Wilson Combat modules to add some weight depending on end-user preference for weight and some degree of felt recoil mitigation, which was one of the main benefits of the TXG grip.

    Overall, an amazing product, and a great upgrade for those looking to utlize a grip with the 1911 grip angle and integrated flared magwell. Looking forward to future iterations of this product as well as continuing to run this one hard.

    This is a great grip module, I purchased one to try specifically on my Sig P250 and it works, I just had to upgrade my trigger to the modern thin P320(M17/18) trigger because the old stock “Fat Trigger” of the P250 wouldn’t pull far enough to fire. The grip doesn’t come with a Magazine Release so you must also source that somewhere else. I really like the feel and the look of this grip module, it fits my hand well and I use the Medium Sig Grip Modules.

    This is a really well built grip module the tan color matches the stock sig coyote grip module very well. I purchased one to try specifically on my Sig P250 and it works! It will not work with the original, pre upgraded sig fat trigger from the P250, however it does work well with both the sig lightened (M17/18) style thin trigger and the sig flat faced trigger. The grip does not come with the Magazine Release so you will need to purchase one of those separately. This Grip works with the Sig P250 Fire Control Units as long as you also upgrade the trigger away from the stock fat trigger, for a hammer fired M1811 style firearm.
