Glock 21 Barrel
The Glock 21 Barrel (SP05362) is a factory OEM replacement barrel chambered in .45 ACP for the full-size Glock 21 and G21 SF pistol. Measuring 4.61 inches and cut with Glock's signature hexagonal polygonal rifling at a 1:15.75 right-hand twist, it delivers the velocity, accuracy, and service life Glock owners expect. The hardened black nitride finish stands up to holster wear and high round counts, and the barrel drops in to Gen 2, Gen 3, and Gen 4 G21 platforms without fitting. A solid choice for replacing a worn or damaged barrel, building a spare slide, or keeping a backup on the shelf.
