Reliability and simplicity have made Glock 21 semi-automatic pistols a favored sidearm for law enforcement, military, and civilian use all over the world. The Glock 21 Gen4 Semi-Auto Pistol is a full-size service pistol, shooting the .45 ACP pistol cartridge, a standard military round for over 100 years with proven knock down power.
The Glock 21 Gen4 Semi-Auto Pistol utilizes a dual recoil spring assembly that substantially increases service life of the pistol, and helps take the snap out of recoil, reducing muzzle flip for faster follow up shots. A modular back strap allows shooters to instantly customize the grip to an individual shooter’s hand size, or to cold weather gloves.
Rough grip texturing on the Glock 21 Gen4’s polymer frame provides a sure hold on the pistol when hands are wet or sweaty, and the enlarged magazine catch is reversible, accommodating left- or right-handed shooters. An integral accessory rail in front of the trigger guard allows for the attachment of a plethora of aftermarket tactical flashlights or laser sights.
The dovetailed rear sight is drift adjustable and has a white outline around its notch; the fixed front blade has a white dot. Sight acquisition is quick in any light. The Glock 21 Gen4 Semi-Auto Pistol is an ultra-reliable handgun that is easy to learn how to operate and maintain, making it an ideal choice for self-defense, whether it be for field carry, home defense, or bear protection in the back country.
The model Glock 21 Gen4 comes with three standard 13-round magazines, or three 10-round magazines that comply with various city or state restrictions on magazine capacity.
