How To Install a Shockwave Grip on Your Rossi Brawler

Sometimes, you can’t just leave well enough alone. As a fan of silly novelty guns, I recently purchased a Rossi Brawler. It’s a single-shot ‘pistol’ that fires either .410 or .45 Colt. Much like the Judge, it brings .410 power to a pistol configuration. The gun itself is a novelty with very little practical application. That’s fine with me. I like fun guns. The Rossi Brawler reminded me of a pirate gun, but it occurred to me that it could look a lot more like a pirate gun with a shockwave grip. 

I love shotguns, so I had more than one of these extra grips just kind of bouncing around. The two items didn’t seem impossible to combine. Sometimes, your dreams are only a dremel away. With this in mind, please remember that if you decide to undertake this, you are likely violating the gun’s warranty. It seems like it won’t cause harm, but don’t hold me responsible if this breaks your gun. 

The risk is 100% on you. It works fine on my gun, but I’m not taking responsibility for anything you do. 

The Rossi Brawler Shockwave 

These grips are made for both Mossberg and Remington shotguns. Mine is a Mossberg variant. I can’t tell you if the Remington one works, but the Mossberg model works fine. You’ll need the grip and stock bolt to install this onto your Brawler. That stock bolt has two washers. I had to add one additional washer for it to fit properly. 

You’ll need a dremel with a cutting wheel, a Phillips-head screwdriver, and two Allen wrenches of appropriate size. I also suggest all proper PPE be worn to use a Dremel. With all this in tow, we first need to remove the grip from the Brawler. It’s very simple. 

We have a Phillips head screw at the bottom. That removes the rubber portion. Inside the rubber portion sits a mount that uses a bolt with an Allen head. Get that out of there. Now, the grip is fully removed. I found that the stock Shockwave bolt for the Mossberg 500 fit perfectly.

It’s Dremel Time 

Hold the Shockwave grip up to the back of the Brawler. The Shockwave grip has this fun little protrusion designed to mate with the rear of the Mossberg series shotguns. That protrusion keeps the Shockwave from perfectly mating with the rear of the Brawler. This is where our Dremel makes its debut. 

We’ll slowly erase the upper 1/3rd of the protrusion with the Dremel and a good cutting wheel. It’s not a big deal if you cut more than that. You just need to cut enough to keep the protrusion from blocking the grip from sliding into the slot. Once the grip can fit into the slot, we can bolt things down. 

Slide the bolt with the extra washer in place and tighten it down. The Shockwave grip is going to want to twist, so make sure you hold it tight. Once the bolt gets tight enough, it won’t twist or move. 

The Brawler Shockwave 

The Brawler went from pirate pistol to super pirate pistol. Tally—and I cannot stress this enough—HO!

The Brawler with the Shockwave grip handles fine. Using the iron sights is admittedly a little harder. It feels odd, but it’s perfect with a red dot. I think Rossi should consider adding a grip like this to the Brawler as a stock option. It just looks and feels so right!
