Made in the United States, this G21 Gen4 is marked "USA" on the slide with "MADE IN USA GLOCK, INC., SMYRNA, GA" on the frame, indicating domestic production in Glock's Smyrna, Georgia facility.
The 4.61-inch steel barrel uses Glock's octagonal polygonal rifling specific to .45 Auto, paired with a bore in excellent condition. This combination reflects minimal prior use and clean internal surfaces.
The Gen4 polymer frame features the RTF texture with finger grooves for a secure hold. Controls are straightforward, with a left-side magazine release and the Safe Action system with a trigger safety tab. The slide wears rear-only vertical serrations.
Sighting is via fixed polymer units: a white-dot front and a white-outline rear. A Glock universal accessory rail is integrated into the dust cover.
The pistol is set up for high-capacity use with the included KRISS MAG-EX2 30-round magazine and also comes with three Glock factory 13-round magazines. It is compatible with KRISS MAG-EX2 45 extended magazines.
