About Glock 21C

The Glock 21C is a compensated variant of the standard Glock 21, chambered in the powerful .45 ACP caliber. It features integrated barrel porting, which vents gases upwards to significantly reduce muzzle flip and felt recoil. This compensator system enhances the shooter's control and accuracy, particularly during rapid fire. The Glock 21C retains the high magazine capacity and robust build of the original Glock 21, making it a strong choice for those who require the stopping power of the .45 ACP round in a more controllable and user-friendly package. This combination of power, precision, and manageability makes the 21C a favored option for self-defense, law enforcement, and sport shooting.
