What's Included
- Glock 21 Gen3 .45 ACP pistol
- 1x 13-round factory Glock .45 Auto double-stack polymer magazine
The Gen3 frame features finger grooves, thumb rests, and a pebble texture for a secure hold. Controls are left-side-only for the slide stop and magazine release, consistent with the Gen3 configuration. The frame is matte black polymer and includes the Glock Universal single-slot accessory rail.
The 4.6 in steel barrel is cold hammer forged with polygonal rifling and a nitrided (ferritic-nitrocarburized) finish. The steel slide shares the ferritic-nitrocarburized finish and wears matte black color with rear-only vertical serrations.
Sights are the factory fixed polymer set, with a white dot front and a square-notch rear. The pistol is striker-fired and operates on a short-recoil, tilting-barrel system with Glock's integrated trigger, firing pin, and drop safeties.
Markings include "MADE IN AUSTRIA" and "GLOCK, INC., SMYRNA, GA." The frame and barrel carry matching serial numbers, adding to the completeness of this example.
