The Rossi Brawler is a single-shot, break-action pistol chambered in .300 AAC Blackout. It has a 9-inch barrel with a 5/8x24 threaded muzzle and an Olive Drab Green applied finish over the frame.

Owners of the Brawler like how few moving parts a break-action design has, which keeps the gun simple to clean and less prone to malfunction than a semi-automatic pistol. Some new owners note that a single-shot .300 AAC Blackout pistol has sharp recoil for its size and takes practice to reload quickly from a break-open action under time pressure.

The 9-inch barrel keeps the gun compact and light to carry, and the Picatinny rail makes it straightforward to add a red dot for faster target acquisition. The fixed sights are basic but functional as a backup, and the Olive Drab Green finish is popular among owners who want something other than plain black or stainless.

On value, the Brawler is often picked up as an inexpensive way to shoot .300 AAC Blackout out of a pistol-format gun, and the threaded muzzle opens the door to muzzle devices without committing to a rifle-length build. It is generally seen as a novelty or range-day platform rather than a primary defensive pistol, given the single-shot capacity.
