This Gen 3 standard-frame G21 is chambered in .45 ACP and built around a 4.61 inch barrel. The magazine capacity is 13+1, delivering a full-size configuration in Glock's proven .45 Auto platform.
The barrel is cold hammer forged with polygonal rifling. This setup is consistent with Glock's Gen 3 production and supports the excellent bore condition noted on this pistol.
Controls and slide features align with the Gen 3 pattern: a standard, left-side, non-reversible magazine release; Glock Safe Action system; rear-only slide serrations; and an external extractor that also functions as a loaded-chamber indicator.
The pistol includes fixed Glock sights with a white-dot front and white-outline rear. The polymer frame incorporates an integral single-slot accessory rail on the dustcover. Markings include "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." with an "AT" stamp on the barrel hood.
