A Drop-In Barrel That Delivers Custom Pistol Performance
Brownells Edition barrels for Glock® are built to rigorous specifications set by noted self-defense instructor Matt Jacques. Proprietor of Victory First, a company providing real-world training to law enforcement personnel, a U.S. Marine, and a retired law enforcement officer himself, Matt knows a thing or two about what makes a reliable, consistent-shooting, accurate pistol barrel. At the same time, Brownells Edition barrels are designed to right drop into factory Glock slides.
Brownells Edition / Victory First Barrels are machined from high-grade 416R stainless steel by skilled American craftsmen and are thoroughly tested to ensure impressive accuracy and reassuring reliability in your Glock® pistol.
For maximum compatibility with the Glock® you already have in your gun safe, our barrels are compatible with Gen1 through Gen4 Glocks.
- Drop-in fit to most Glock® slides
