Zaffiri Precision Blowhole Compensator for Glock 17/19 – Black

The Zaffiri Precision Blowhole Compensator redirects muzzle gases upward to counteract recoil and reduce muzzle rise during rapid fire. Designed specifically for Glock 17 and 19 models, this comp helps maintain sight alignment through follow-up shots without requiring slide modifications or specialized recoil springs in most configurations.

The Blowhole installs on factory-threaded barrels with 1/2x28 threading. Machined from steel with a durable black finish, it adds minimal length to your slide profile while delivering measurable recoil reduction. No permanent modifications required—simply thread onto a compatible barrel and secure with the included set screw. Verify proper slide-to-comp clearance during installation and function-test with your carry ammunition before defensive use.
