What’s Included
- 2 × 13-round Glock factory steel-lined polymer magazines
This Gen 2 variant retains the early three-pin frame, narrow slide-stop lever, and straight frontstrap—features that changed in later generations. Without finger grooves or an accessory rail, the pistol offers the original grip profile preferred by many shooters and collectors.
The Tenifer salt-bath nitrided slide and barrel provide excellent resistance to wear and corrosion while maintaining the classic matte black appearance. Rear slide serrations give a secure purchase for charging, and all markings remain crisp, including the “MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA.” proof.
Factory polymer sights feature a white front dot and rear outline that are drift-adjustable for windage. The striker-fired action delivers the consistent trigger pull that helped define Glock’s reputation for reliability.
With a 13+1 capacity in .45 ACP, the Glock 21 was groundbreaking when introduced, and this early Gen 2 example continues to stand out for its combination of firepower, durability, and collectible status.
