Zaffiri Precision Glock19 Gen5 Barrel Features The Zaffiri Precision Integrated Blowhole System reintroduces the brand s time-tested ZPS.1 slide integration combined with a Blowhole compensator design built directly into the barrel. An angled port and back-bored bore work together to push more propellant gas up and out of the action during firing which helps manage muzzle rise without relying on a separate threaded comp. Because the carbon and gas are directed away from the slide s internal surfaces the system also reduces carbon buildup that would otherwise accumulate with standard barrel designs. This means less maintenance and cleaner function between cleanings for the Glock 19 Gen5 owner. Machined from stainless steel with a stainless finish the barrel is cut to 3.89 with a 1:10 twist rate matching the factory specifications of the Glock 19 Gen5 for a true drop-in installation. At just 6 ounces the barrel adds negligible weight to the pistol while delivering the flat-shooting characteristics normally associated with a threaded compensated setup. Shooters gain these benefits without needing to thread the barrel or attach any external hardware to the muzzle. The Zaffiri Precision Integrated Blowhole System is a straightforward upgrade for Glock 19 Gen5 owners looking for reduced recoil and cleaner function.
