True Precision Threaded Barrel 9MM Gold Titanium Nitride for Glock 43/43X (TP-G43B-XTG)

A quality barrel is the foundation of reliable accuracy, and the True Precision Threaded Barrel for Glock 43/43X is built to outperform factory specs from the ground up. This drop-in 9mm barrel ships ready to install—no gunsmithing required—and comes finished in durable Gold Titanium Nitride coating. If you run a compact Glock 43 or 43X and want to upgrade to something engineered specifically for tighter tolerances and better shot-to-shot consistency, this US-made barrel delivers the fit and finish upgrades you're looking for.

The barrel features a proprietary 6-groove broach cut rifling with 1/10 right-hand twist, designed to stabilize 9mm projectiles reliably across all standard ammo types—including cast lead rounds if you reload. The threaded version comes with a competition-style 1/2x28 thread protector featuring an integral Viton O-ring lock to keep it secure and seated. True Precision engineered this barrel with a fully supported SAAMI-spec chamber and refined it beyond OEM standards: improved chamfers, radius cuts, and overall geometry that tightens up the fit between barrel and slide for less wiggle and more consistency shot after shot.

Built and sourced in the USA from certified 416R stainless steel, this barrel represents the kind of precision manufacturing that rewards shooters who care about the details. Whether you're putting rounds downrange at the range or carrying a tighter, more reliable platform, a drop-in barrel swap is one of the highest-return upgrades you can make to a Glock.
