The Glock G21 Gen5 MOS .45 ACP Rebuilt pairs Glock’s proven full-size .45 Auto platform with the modern Modular Optic System, giving shooters a dependable sidearm that is ready for today’s optics-ready slide setups. This rebuilt model features Glock Marksman Barrel (GMB) technology with a 4.61" barrel, fixed sights, and a black nDLC slide over a textured polymer frame with interchangeable backstraps for a secure, adaptable grip.

This Glock G21 Gen5 MOS is well suited for home protection, duty use, and extended range sessions where the soft-shooting .45 ACP and full-size frame offer controllable recoil and comfortable handling. The ambidextrous controls and integrated Picatinny rail make it easy to configure with lights or other accessories, while the rebuilt designation offers a cost-conscious way to own a factory-serviced Glock. Glock’s reputation for durability, simplicity, and long service life underpins every aspect of this pistol.
