The True Precision Black Nitride Threaded Barrel for Glock 48 is a drop-in upgrade for shooters looking to add suppressor capability or a muzzle brake to their carry or range gun. This 4.68" barrel ships with a Viton high-heat integral O-ring lock thread protector and threads in at 1/2x28, the standard for 9mm suppressors and accessories. Installation is straightforward—it's designed as a simple drop-in replacement—and it's manufactured entirely in the USA from 416R stainless steel.
What sets True Precision barrels apart is their proprietary broach cut rifling design, engineered specifically for tighter tolerances and improved accuracy potential right out of the box. The 6-groove rifling runs at 1/10 RH twist and is safe for all ammunition types, including cast lead rounds—a big advantage if you reload or shoot budget-friendly lead projectiles. The crown and chamber work meet SAAMI spec, and the barrel features refined geometry throughout: added chamfers, improved radius cuts, and tighter overall fit than stock Glock barrels, all contributing to more consistent performance at the range.
The black nitride finish is durable and corrosion-resistant, holding up to frequent use and cleaning. Whether you're suppressing your Glock 48 for reduced noise, adding a muzzle brake for faster follow-up shots, or simply upgrading to a more precise barrel for target work, this True Precision option delivers Made-in-USA quality without the factory compromises.
