True Precision 9MM Gold Titanium Nitride Threaded Barrel for Glock 19 (TP-G19B-XTG)

The True Precision 9MM Gold Titanium Nitride Threaded Barrel for Glock 19 is a drop-in replacement barrel designed to boost accuracy and versatility in your 9mm pistol. Built as a direct fit for Glock 19, 19X, and Model 45 frames across generations 1–5, this threaded barrel gives you the option to run a suppressor while maintaining True Precision's reputation for tight tolerances and thoughtful engineering. The Gold Titanium Nitride finish is as durable as it is distinctive, protecting the barrel while offering a professional look on the range or in competition.

True Precision engineered this barrel with a proprietary broach cut design and 6-groove rifling that handles any ammunition type you feed it—including cast lead rounds—without compromise. The 9mm 1/10 right-hand twist rifling is paired with a 1/2x28 thread pitch, standard for 9mm suppressors, and comes ready to install with a high-heat Viton O-ring lock thread protector included. The 11-degree competition-style target crown is cut for precision, and the fully supported SAAMI-spec chamber ensures reliability and safety across the board.

What sets this barrel apart is the attention to detail: improved fit over OEM, added chamfers, and refined radius cuts throughout make installation straightforward and function flawless. Manufactured entirely in the USA from certified 416R stainless steel, it's the kind of upgrade that rewards shooters serious about accuracy, whether you're running suppressed, competing, or just raising your standard for what a Glock barrel can be.
