The True Precision 9mm Black Barrel with Thread Protector is a precision-engineered replacement barrel built for Glock 17 Gen 1-4 pistols. If you're running a suppressor-ready setup, upgrading your duty gun, or just want a factory-quality barrel from a US manufacturer, this threaded option gives you the flexibility to add muzzle devices without sacrificing reliability. True Precision, based outside Atlanta, designs and machines their parts in-house using American materials and craftsmanship—no overseas production shortcuts.

This 9mm barrel is threaded 1/2x28, the industry standard for 9mm suppressors and muzzle brakes, so you'll have no trouble finding accessories that fit. The 1:10 left-hand twist rifling is optimized for typical 9mm projectiles and delivers consistent accuracy across a wide range of loadings. The barrel comes with a thread protector, so your threads stay clean and protected until you're ready to mount a suppressor or other device.

Glock shooters who want a quality aftermarket barrel will appreciate that True Precision engineers every part with personal defense and duty use in mind. Drop-in fit is straightforward on Gen 1-4 Glock 17 frames, and the black finish matches the aesthetic of most duty and tactical builds. Whether you're prepping for suppressed shooting, replacing a worn barrel, or building out a modern carry gun, this is a no-nonsense barrel from a maker who understands what works in the real world.
