Drop-in threaded 9mm barrel for Glock 19 Gen 1-4 pistols. True Precision machines this barrel from American-sourced certified steel with a brushed stainless steel finish — a clean two-tone look against a black slide. The 1/2x28 muzzle threads accept most 9mm compensators, flash hiders, and suppressors.
Fit: Glock 19 Gen 1-4 only. Will not fit Gen 5 (different barrel profile). True Precision's proprietary broach-cut rifling delivers tighter group sizes than the factory G19 barrel while feeding reliably across FMJ and JHP profiles.
Run 150-200 rounds of FMJ to settle the new barrel before defensive carry. Re-verify zero on any optic-equipped slide and confirm reliable lock-up with your preferred recoil spring weight.
