Zaffiri Precision Blowhole Compensator for Glock 17/19 – Black Finish

The Zaffiri Precision Blowhole Compensator is a single-port muzzle device designed to reduce muzzle rise and keep your Glock 17 or 19 flat through rapid strings of fire. The vertical port redirects gas upward to counter recoil forces, allowing faster sight recovery between shots. This comp is built for competition shooters and defensive carry users who want repeatable accuracy without the bulk of larger multi-port designs.

The Blowhole threads directly onto factory-length Glock barrels with 1/2x28 threading. No permanent modifications required. Machined from steel with a black nitride finish for corrosion resistance and wear protection. The compact profile maintains standard holster compatibility with most open-bottom holsters.
