Glock, Oem Barrel G23, .40 S&W, 4.02 in, Factory Finish

The Glock OEM Barrel G23 40SW is a factory replacement barrel for the Glock G23 series that brings the trusted polygonal rifling Glock is known for to your .40 S&W pistol, and if you shoot defensive loads, competition rounds, or train at the range you'll notice reduced barrel fouling and a tighter bullet-to-barrel fit that helps maintain consistent velocity shot to shot. This 4.02" OEM barrel matches Glock fitment and headspace for reliable lock-up and feeding, so it drops in without gunsmithing on G23 frames or compatible models, and its durable construction resists wear from high-round-count use whether you're a law-enforcement professional, duty gun owner, or a serious recreational shooter. The design also pairs well with suppressor-ready setups where reduced residue in the bore makes maintenance easier and velocity consistency assists with point-of-impact retention; note that no FFL transfer is required for this non-NFA component.
