Faxon Firearms Duty Series Glock 19 Threaded 9mm Barrel, Black Nitride 1/2x28 GA910N19NGQ-T

Product Description

Upgrade your Glock 19 with Faxon Firearms Duty Series pistol barrels, machined 100% in-house from stress-relieved 4150 CMV steel and finished in a black Nitride coating for enhanced lubricity, extended barrel life, and excellent resistance to surface wear. Designed as a true drop-in replacement, this barrel fits factory-spec slides with no gunsmithing required while delivering better-than-factory tolerances for a consistent, tighter lockup than OEM. Conventional rifling and a precision 11-degree target crown help support reliable accuracy while remaining compatible with a wider range of ammunition, including cast lead.
