Ballistic Advantage | Glock 19 Premium Series Barrel | 9mm 4.5″

The Ballistic Advantage Premium Series pistol barrel is a threaded 4.5″ replacement designed for Glock 19 Gen 3-5 pistols. Constructed from hardened 416R stainless steel and finished with a QPQ corrosion-resistant coating in a copper color, the barrel is honed, lapped, and tumbled to deliver consistent bore quality.
