Drop-in threaded 9mm barrel for Glock 17 Gen 1-4 pistols. True Precision machines this barrel from American-sourced certified steel and finishes it with a hard-wearing black DLC coating for corrosion resistance and a deep matte appearance. The 1/2x28 muzzle threads accept most 9mm compensators, flash hiders, and suppressors.

Fit: Glock 17 Gen 1-4 only. Will not fit Gen 5 (different barrel profile). The 1:10 left-hand twist rifling is engineered for stable bullet profiles across 115gr, 124gr, and 147gr loads.

• Thread pitch: 1/2x28

Run 150-200 rounds of FMJ through the new barrel to settle it before relying on it for defensive carry. Re-verify zero on any optic-equipped slide and confirm reliable lock-up under your preferred carry ammunition.
