The Faxon Match Series 9mm barrel for the Glock 17 Gen 5 (brand part no. GB910N175LGQ-T) is a drop-in upgrade machined 100 percent in-house from 416-R stainless steel. Faxon finishes it with a black Nitride or PVD coating for added lubricity, barrel life, and resistance to surface wear, then rifles it conventionally so it is safe to run a wider range of ammunition, including cast lead. At 4.5 inches, it matches the factory Glock 17 Gen 5 barrel length, drops into a factory-spec slide with no gunsmithing required, and ships threaded so shooters can add a compensator directly.
