The Rosco Bloodline 9mm 3.4 Inch Non-Threaded Barrel is engineered as a drop-in replacement for Glock 43 pistols. While installation is straightforward, consulting a local gunsmith is recommended if you have questions about the process. This barrel accepts SAAMI-approved, factory-new ammunition only.
Rosco Manufacturing’s Bloodline barrels are match-grade components that improve accuracy and performance in stock Glock pistols. Each barrel is constructed from 416R stainless steel, then broached, honed, polished, and melonited for durability and reliability.
