The True Precision Gold TiN threaded barrel for Glock 48 is a precision drop-in upgrade designed to improve accuracy and versatility for shooters who run suppressors or muzzle devices on their carry or competition pistol. Built entirely in the USA from 416R stainless steel, this barrel combines a proprietary broach-cut rifling design with a 1/2x28 threaded muzzle, giving you the foundation for reliable suppressed shooting without sacrificing reliability or ease of use.

True Precision engineered this barrel around real shooter needs: the six-groove rifling accepts all ammunition types—including cast lead rounds—safely, so you're not locked into factory ammo for practice or matches. The barrel's advanced broach-cut geometry is intended to deliver improved accuracy potential over factory Glock barrels. Dimensionally, the 4.68-inch length (breechface to muzzle, not including the thread protector) pairs with a SAAMI-spec chamber and improved fit work: added chamfers and radius cuts throughout make for a better lockup in the frame than OEM, which matters for consistency on the range or in defensive scenarios.

Installation is straightforward—this is a drop-in design with no gunsmithing required. The barrel ships with a Viton high-heat integral O-ring lock thread protector to keep your threads safe when running unsuppressed or between hosts. The Gold TiN finish is a choice among True Precision's specialty coatings, offering durability and corrosion resistance for hard use.
