True Precision TPG43BXTBL Glock 43/43X 9mm Luger 3.90" Threaded Barrel - Black Nitride

The True Precision TPG43BXTBL is a match-grade drop-in threaded barrel purpose-built for the Glock 43 and Glock 43X chambered in 9mm Luger. Machined from certified 416R stainless steel and finished in a low-friction Black Nitride coating, this American-made barrel is engineered as a direct replacement for the factory Glock barrel with no fitting required.

The overall length measures 3.90" with a 1/2x28 threaded muzzle ready for a compensator or suppressor, and the bore features a proprietary broach-cut 6-groove rifling pattern at a 1:10" RH twist that is suitable for all 9mm ammunition including cast lead loads. The Black Nitride QPQ finish provides excellent lubricity along with corrosion and wear resistance, while the barrel is heat-treated to a 42-44 HRC hardness rating for long service life. Advanced cuts, chamfers, and a polished feed ramp deliver reliable feeding and unmatched accuracy straight out of the box.

No sights are installed, allowing the end user to use their existing Glock 43/43X slide sights or run the slide with an aftermarket optic-cut configuration. This barrel is a drop-in upgrade component only and does not include a slide, frame, or magazine.
