The Faxon Duty Series Threaded Barrel For Glock 17 Gen 5–6 9mm is a drop-in upgrade built for shooters who want dependable performance with the added versatility of a threaded muzzle. Machined from stress-relieved 416R stainless steel and finished in a full salt bath nitride treatment, this barrel is designed to deliver long-term durability, smooth function, and consistent accuracy in a full-size Glock platform.

This model features a 4.94" threaded barrel with conventional button rifling and a 1:10 twist, making it compatible with a wide range of 9mm loads, including cast bullets. The 11-degree target crown helps maintain precision, while the 1/2x28 threads are ready for compensators, suppressors, or other muzzle devices. With tighter-than-factory tolerances for improved lockup and a true drop-in fit for Glock 17 Gen 5–6 slides, it is well suited for range work, training, and duty-style use where reliability and repeatable performance matter. Faxon is known for careful machining and thoughtful design, and this barrel reflects that reputation in both feel and function.
