True Precision Threaded Barrel for Glock 43 - Copper Titanium Nitride Finish

The True Precision threaded barrel for Glock 43 puts genuine American engineering into your carry pistol's foundation. Built right here in the USA from 416R stainless steel, this drop-in barrel swaps in easily and pairs with either the Glock 43 or 43X—no gunsmithing required. Whether you're running suppressed, threaded for a compensator, or simply want upgrade-grade accuracy potential, the Copper Titanium Nitride finish delivers durability and corrosion resistance in a professional, subdued look that works across duty and personal defense roles.

True Precision engineered this barrel with a proprietary broach cut and 6-groove rifling designed to shoot tighter groups than factory barrels—and the design accepts all ammo types safely, including cast lead rounds. The rifling twist (1/10 RH) and full SAAMI chamber support standard 9mm loads across the velocity and pressure spectrum. If you thread it, you get a competition-style 11-degree target crown and a high-heat Viton O-ring locking thread protector included, so your suppressor or brake stays put.

This is the kind of foundational upgrade that Glock shooters often overlook: it's not flashy, but a quality barrel that shoots flatter and lasts longer matters for anyone serious about accuracy and reliability. Made by Americans, in America, without outsourcing—exactly what True Precision was founded to deliver.
