Brownells Pistol Fluted G17 Gen1-4 9mm Luger 4.02'' Barrel

The Brownells Pistol Fluted G17 Gen1-4 9mm Luger barrel is a match-grade replacement or upgrade for shooters running Glock 17 pistols from Gen 1 through Gen 4. Built from hardened 416R stainless steel and finished with a Black Nitride coating, this 4.02" barrel delivers the precision and durability you'd expect from an American-made component designed to outlast a factory original. The fluted design reduces weight without sacrificing rigidity, and the button-rifled, 1-in-10" right-hand twist is optimized for 9mm Luger ballistics.

If you're replacing a worn barrel after years of range use or looking to tighten up your accuracy with a quality upgrade, this Brownells barrel is a straightforward bolt-in solution. The Black Nitride finish resists both corrosion and surface wear — practical protection whether you're running suppressed, shooting steel, or pushing rounds downrange in variable conditions. It's the kind of no-nonsense upgrade that serious Glock shooters reach for when the factory tube needs to go.

A threaded version with 1/2"-28 TPI threads is available separately if you're building a suppressed setup. Either way, you're getting a Made in USA barrel from a company that knows the details matter.
