True Precision TPG19BXBL Glock 19/19X/45 9mm Luger 4" Fluted Drop-In Barrel - Black Nitride

The True Precision TPG19BXBL is a drop-in aftermarket 9mm Luger pistol barrel engineered as a direct replacement for Glock 19, 19X, and Glock 45 pistols across Gen 1-5. Machined from stainless steel with a broached 6-groove rifling pattern at a 1:10" RH twist, this barrel delivers consistent accuracy and supports all standard 9mm ammunition, including 9x19mm NATO loads.

The 4" fluted profile sheds unnecessary weight and helps dissipate heat during high-round-count shooting, while the Black Nitride finish provides excellent corrosion resistance and a low-friction bore surface. Designed as a true drop-in barrel, no gunsmith fitting is required for installation into a compatible Glock slide. Sights are not included.
