The Zaffiri Precision Glock 19 Gen 3 barrel is a drop-in replacement barrel in 9mm with a black nitride finish (Zaffiri Precision part no. BA-G19G14-FC-BN). Zaffiri Precision cuts it from 416R stainless steel and finishes the muzzle flush with the slide and crowned, which protects the rifling and gives the pistol a clean look. Conventional rifling keeps it friendly to a wide range of ammunition, including cast lead. It is made in the USA for shooters who want a tighter, better-finished barrel without changing the rest of the pistol.

Key Specifications

• The fit is the Glock 19 Gen 3, a drop-in replacement for the factory barrel.
• The caliber is 9mm Luger, matching the factory chambering of the Glock 19.
