The True Precision Stainless Steel 9mm Barrel with Thread Protector is a drop-in replacement barrel built for Glock 43 and 43X owners who want better accuracy than their factory setup. Machined from certified 416R stainless steel and 100% manufactured in the USA, this threaded barrel features True Precision's proprietary broach cut design and 6-groove rifling—the kind of engineering that separates a precision upgrade from a basic swap. Whether you're fine-tuning a carry gun or building a more accurate 9mm platform, this barrel delivers the kind of fit and performance that justify the step up from OEM.

The threaded version comes ready to run with a Viton high-heat O-ring lock thread protector included, so you're not hunting for parts before installation. The 1/2x28 threads and 1/10 RH twist rifling are spec'd for all 9mm ammunition types, including cast lead—no ammunition restrictions. A fully supported SAAMI chamber and 11-degree competition-style target crown round out the package, giving you a barrel that's both safe and inherently more accurate than stock.

True Precision spent time on the details other manufacturers skip: improved chamfers, radius cuts, and overall fit geometry that noticeably outperform OEM tolerances. The drop-in design means minimal gunsmithing knowledge required, making this an accessible upgrade for shooters who want real results without sending their gun to a gunsmith.
