The Zaffiri Precision G19 Gen 5 9mm Ported Barrel in Gold is an aftermarket upgraded barrel designed for Gen 5 Glock 19, 19X, and 45 pistols using Zaffiri Precision's ZPS.P ported slide.
This barrel is chambered in 9mm and features a 1:10 twist rate. The ported design helps reduce muzzle flip and improve recoil control. It has a flush crown, meaning the end of the barrel is flat with a slight inward angle. The feed ramp is polished for smoother bullet feeding, and a “ZP” logo is machined on the port side of the barrel. The barrel is made from 416R stainless steel with a Titanium Nitride (TiN) gold finish. It has been stress relieved and heat treated for added durability. Manufactured in the U.S.A., this barrel measures 3.9 inches in length.

Note: This barrel is NOT compatible with Zaffiri Precision ZPS.2, ZPS.3 slides, or slides from other manufacturers.
