Rosco Bloodline 9mm 3.4" Non-Threaded Barrel for Glock 43/43X

The Rosco Manufacturing Bloodline 9mm barrel is a non-threaded 3.4-inch replacement barrel for Glock 43 and Glock 43X pistols. It is machined from 416R stainless steel, a grade chosen for machinability and corrosion resistance compared with standard carbon steels. Each barrel is broached, honed and polished, and receives a melonite nitride finish that hardens the surface and gives it a black appearance.

The barrel uses a 1:10 twist rate, matching Glock's factory specification for stabilizing standard 9mm projectiles. It is designed as a drop-in fit for the Glock 43 and 43X, and the manufacturer rates it for SAAMI-approved factory new ammunition. Rosco recommends having a local gunsmith review fitment if the installer has questions.
