Zaffiri Precision Integrated Blowhole System Barrel Features The Zaffiri Precision Integrated Blowhole System barrel reintroduces the IBS design combining the time-tested ZPS.1 slide integration with the Blowhole Compensator to manage gas without requiring a threaded barrel or external comp attachment. An angled port and back-bored barrel design push more gas up and out of the slide which reduces carbon buildup inside the action over time. This gas management also helps keep the pistol flatter shooting reducing muzzle rise between shots for faster more controlled follow-up shots. Machined from stainless steel and finished in Black Nitride the barrel resists wear and corrosion while maintaining a clean understated appearance. A 1:10 twist rate stabilizes a wide range of 9mm loads giving shooters flexibility in ammunition choice without sacrificing accuracy. At 3.89 in length the barrel matches the Glock 19 Gen5 s factory dimensions allowing it to drop in without modification to the slide or other components. Weighing roughly 6 oz the barrel adds no meaningful weight to the pistol while delivering the recoil-taming benefits of a compensated system. For Glock 19 Gen5 owners who want flatter shooting performance without going to a threaded barrel setup this Zaffiri Precision barrel offers an elegant integrated solution.
