Glock 21 Barrel

Factory Glock 21 Barrel

This is a genuine Glock barrel for the Glock 21, the company's full-size .45 ACP pistol. It is the part to buy when you want to replace a worn or damaged barrel, keep a spare on the bench, or return a pistol to factory configuration after running an aftermarket barrel. Glock 21 owners who want the original part rather than an aftermarket copy will find it here.

Features

• Chambered In .45 Auto — The hood is stamped 45 AUTO, the same cartridge sold as .45 ACP, which is what the Glock 21 is built to fire.
• Genuine Glock Manufacture — The Glock logo and AT (Austria) marking are stamped on the hood, identifying it as a factory part.
• Polygonal Rifling — The bore uses rounded, hexagon-shaped rifling in place of sharp cut lands and grooves, the rifling style Glock uses in its factory barrels.
• 4.61-Inch Barrel Length — This is the full-size length the Glock 21 slide was designed around.
• Black Steel Construction — The steel barrel has a dark black finish matching the factory look of the pistol.
• Integral Locking Lug — The cam lug under the chamber tilts the barrel to unlock it from the slide during the recoil cycle, as on the original barrel.
• Serialized Hood — A factory serial number is stamped on the side of the hood, as on the barrel originally shipped in a Glock pistol.
• Uses Your Existing Parts — The barrel installs in the slide with your current recoil spring assembly during a normal field strip.

Fit and Installation

The barrel is made for the Glock 21 slide in .45 ACP. Installation happens during a standard field strip: remove the slide, lift out the recoil spring assembly and old barrel, then set this barrel in place and reassemble. Glock has made the 21 in several generations and variants, so confirm your pistol's model before ordering, and function-check the pistol before firing live ammunition.
