The 21C is the compensated variant of the Glock 21, featuring twin barrel and slide ports from the factory. This ported barrel system is part of the original design and is correctly matched to the ported slide on this example.
Gen3 features include the textured grip with finger grooves, a non-interchangeable backstrap, and a single-slot Glock accessory rail. The slide has rear serrations, and the pistol uses Glock's Safe Action striker-fired system with an integral trigger safety and a left-side magazine release.
Sights are the standard fixed polymer set with a white dot front and white U-notch rear. The barrel is steel, the frame is polymer, and the pistol carries the Austrian origin marking: "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA."
This model is California roster-listed and configured at 10+1 capacity. Glock discontinued factory "C" models in 2013, making original 21C examples noteworthy for buyers seeking a genuine factory-compensated configuration.
