Brownells
The Brownells Pistol Barrel for Glock 20 with 9/16"-24 threads is a match-grade replacement tube built for shooters who demand accuracy and reliability from their G20. Whether you're swapping out a worn factory barrel, building a custom pistol on a Polymer80 frame, or assembling a gun around a Brownells slide, this barrel delivers the precision fit and performance you need. It's compatible with all generations of the Glock 20 and functions as a true drop-in—no gunsmithing required on most builds.
Machined from 416R stainless steel to exacting tolerances, this barrel features a tight lockup that supports consistent accuracy shot after shot. The button-rifled bore sports a standard 1-10" right-hand twist with 6 grooves, making it suitable for both jacketed and non-jacketed practice ammunition. The threaded muzzle (9/16"-24 TPI) lets you mount a compensator or suppressor, giving you flexibility for your specific shooting setup.
Durability is built in: the Black Nitride finish is hard-anodized to resist wear and corrosion, protecting the stainless steel underneath without adding bulk or weight. This is a barrel designed to handle years of shooting and cleaning without showing its age. Each barrel arrives laser-engraved with its chambering and Glock model designation, so there's no guessing what you've got.
