All our pistol barrels for Glock® / G19 are made from 416-R stainless steel (Match Series) or stress-relieved 4150 CMV steel (Duty series). These barrels are then given a PVD or black Nitride coating to increase resistance to surface wear, lubricity, and barrel life. All barrels are conventionally rifled for a wider variety of compatible ammunition, including cast lead. These pistol barrels drop into factory-spec slides with no gunsmithing required. A more consistent, tighter lockup than OEM is ensured thanks to our better-than-factory tolerances. We offer both threaded and non-threaded barrel options for your Glock® 19. The best part, our pistol barrels are 100% machined in-house.
