Tapco 2-Port Micro Brake Features The Tapco 2-Port Micro Brake threads directly onto any 1/2x28 pattern 9mm barrel giving shooters an easy bolt-on upgrade without needing a gunsmith to fit it. Its two port design vents propellant gas upward and to the sides as the round exits the muzzle which helps counteract muzzle rise and reduce felt recoil on fast follow up shots. Because the brake is sized specifically for 9mm pistols the port geometry is tuned to that cartridge s pressure and gas volume rather than being a generic one-size-fits-all design. This focus on a single caliber helps the brake perform consistently compared to brakes built for multiple chamberings. The compact micro profile keeps the brake from adding significant length to the pistol preserving much of the gun s concealability while still delivering a functional recoil control benefit. A black nitride finish adds corrosion resistance and a hard wearing surface that matches the black finish common on most threaded pistol barrels. This combination of a low profile design and genuine recoil reduction makes the Micro Brake a practical choice for competition shooters and anyone running a threaded 9mm pistol for recreational use. The Tapco 2-Port Micro Brake is available for sale at GrabAGun for 9mm pistols with a 1/2x28 threaded barrel.
