The nine inch barrel for the Glock 20 Gen 3 SF and Gen 4 is designed for shooters who want greater accuracy, stability, and long range performance from their ten millimeter platform. Whether you are updating an existing build or outfitting an MX1 setup, this extended barrel delivers smoother operation, cleaner cycling, and more predictable shot placement.
Constructed from strong American sourced steel, the barrel uses stress relieved CrMoV material that is finished with a protective Black Nitride treatment. This combination offers impressive resistance to corrosion and wear, even during extended sessions or high volume use. The precision button rifling and improved lockup contribute to tighter groups and consistent reliability across a wide range of loads.
The muzzle uses a one half inch by twenty eight threaded design that allows you to attach compensators, suppressors, and various muzzle accessories. A matching thread protector is included to keep the threads secure when attachments are not installed. The one in sixteen right hand twist rate is tailored for ten millimeter stability, providing excellent performance for tactical applications, range work, hunting, or defensive training.
Proudly made in the United States, every barrel is machined with tight tolerances and inspected with detailed quality control processes to ensure a clean fit, dependable accuracy, and smooth function inside your Glock 20 platform.
