Frequently Asked Questions
Which Glock 19 generations is this barrel compatible with?
The True Precision threaded barrel is designed as a drop-in fit for the Glock 19 Gen 3 and Gen 4. It is not designed for the Gen 5, which uses a different barrel profile and lockup geometry. Always verify compatibility with your specific firearm before installation.
What thread pitch does this barrel use, and what muzzle devices will fit?
This barrel features a standard 1/2×28 TPI thread pitch, which is the most common thread spec for 9mm pistol barrels in the US market. This means it is compatible with a wide range of suppressors, compensators, and muzzle brakes designed for 9mm — including popular options from SilencerCo, Dead Air, Griffin Armament, and many others. A thread protector is typically included or recommended when no device is attached.
Will this barrel improve accuracy over the factory Glock barrel?
Yes — True Precision barrels use an advanced proprietary broach-cut rifling process and tighter manufacturing tolerances compared to stock Glock barrels. Most shooters report measurably improved groupings, especially at distances of 15 yards and beyond. The Black Nitride finish also reduces friction and fouling buildup, which helps maintain consistent performance over high round counts.
