The Rosco Manufacturing Bloodline 9mm barrel for Glock 43 is a precision replacement barrel engineered for shooters who want to upgrade their subcompact's performance. At 3.40 inches, this stainless steel barrel maintains the compact profile your G43 was built for while offering the durability and accuracy benefits of a quality aftermarket component. Whether you're fine-tuning your carry gun, running it at the range, or experimenting with different ammunition, a dedicated barrel swap opens up new possibilities for your platform.

Built from stainless steel with a Black Melonite finish, the Bloodline barrel resists corrosion and wear while keeping a professional appearance. The finish is equally at home on a duty-ready concealed carry gun or a range tester.
