Stand-Out Features
- Proven .45 ACP Platform: The GLOCK 21 offers controllable power and the stopping power of the .45 ACP cartridge in a reliable, time-tested design.
- Enhanced Ergonomics: Features a Gen3 frame with a reversible magazine catch and dual recoil spring assembly for improved handling and reduced felt recoil.
- High-Capacity Standard: Comes with a 13-round magazine, providing substantial firepower for its caliber in a duty-sized handgun.
- Safe Action System: Utilizes GLOCK’s consistent trigger pull and three independent safeties for secure carry and confident operation.
- Accessory-Ready: The accessory rail accepts lights and lasers, making it suitable for tactical or home defense roles. Our staff notes it pairs well with an extended slide release for faster, smoother reloads.
