True Precision 9mm Black DLC Threaded Barrel for Glock 43/43X (TP-G43B-XTBC)

The True Precision 9mm Black DLC Threaded Barrel for Glock 43/43X is a USA-made replacement barrel engineered for shooters who demand accuracy and reliability in a compact defensive platform. Built in Georgia from certified American steel, this threaded barrel lets you add a suppressor or muzzle device to your slim-line Glock while maintaining the precise tolerances that matter downrange. True Precision designed this barrel from the ground up for personal defense, which means every dimension and finish choice serves reliability and performance—not marketing.

The black DLC (diamond-like carbon) coating delivers a durable, low-glare finish that stands up to daily carry and regular shooting. Threading is cut with True Precision's proprietary broach design, a process that maintains strict dimensional consistency and contributes to the accuracy potential that separates quality aftermarket barrels from the rest. Because it's manufactured entirely in the USA with domestically sourced materials, you know exactly where your parts come from and who backed them.

Drop-in fitment for the Glock 43 and 43X means installation is straightforward—no fitting or gunsmithing required. If you run suppressed, practice low-light shooting, or simply want to upgrade your carry gun's factory barrel with something built to tighter tolerances, this is a solid choice. True Precision's commitment to design and manufacturing in America shows in every detail.
