The Glock 21C is a compensated variant of the standard Glock 21, designed to enhance shooting performance by reducing muzzle rise and felt recoil. Chambered in .45 ACP, it features an integral compensator with ports cut into the barrel and slide, directing gases upward to counteract muzzle flip. This design facilitates quicker follow-up shots and improved accuracy, particularly in rapid-fire scenarios. The 21C maintains the standard 13-round magazine capacity and incorporates Glock's Safe Action System, ensuring consistent trigger pull and safety. Its polymer frame contributes to a lighter weight compared to traditional steel-framed pistols, enhancing maneuverability. The compensated design is especially beneficial for shooters seeking to manage the robust recoil of the .45 ACP cartridge, making the Glock 21C a preferred choice for those prioritizing control and precision.
