USED Glock 21 Gen4 .45 ACP Pistol – Night Sights, USA Made, Very Good Condition

The Glock 21 Gen4 is a full-size, striker-fired pistol chambered in .45 ACP. It combines a standard 13-round capacity with Glock’s polymer frame, Safe Action operating system, accessory rail, and straightforward control layout. The Gen4 design adds interchangeable backstraps and a reversible magazine catch, allowing the grip and controls to better accommodate different shooters.

This USA-made example is equipped with night sights for improved visibility in reduced-light conditions. Its full-size frame, 4.61-inch barrel, and high-capacity double-stack magazine make it well suited for range use, home protection, and shooters looking for a substantial .45-caliber platform.

The pistol is in very good preowned condition. The supplied photographs show light cosmetic and handling wear but no obvious major damage. One magazine appears to be included; no factory case or additional accessories are shown.
