The G21 Gen4 is a full-size .45 ACP, striker-fired pistol with Glock’s Safe Action system and a 4.61-inch steel barrel. It features a matte black slide with rear serrations and fixed sights: a white-dot front and a white-outline U-notch rear. Standard capacity is 13+1 with the included OEM magazines.

Gen4 ergonomics include the RTF grip texture with finger grooves for consistent purchase and an enlarged, reversible magazine release to accommodate different shooters and reload techniques.

The frame is polymer with two cross pins above the trigger, and it integrates the Glock Universal accessory rail with one cross slot.

The barrel uses polygonal rifling with a 1:15.75 RH twist, optimized for .45 Auto. The rifling and bore are clean and well-defined, supporting the pistol’s excellent mechanical condition.

This is a USA-made example with clear provenance: the slide is marked \"GLOCK 21 Gen4 USA 45 Auto,\" the frame is molded \"MADE IN USA GLOCK, INC., SMYRNA, GA.,\" and the barrel hood carries \".45 Auto\" with the Glock logo.
