The G20C is a factory-compensated variant with aligned barrel and slide ports. These ports are Glock-produced and matched to the slide, providing a true G20C configuration rather than an aftermarket modification.
It is a Gen 3 large-frame model with finger grooves and a single-slot accessory rail. Controls include the standard magazine release and the Safe Action system with three passive safeties. The trigger is the Safe Action design paired with a 5.5 lb connector.
The 4.61 in steel barrel is cold-hammer-forged, nitride-treated, and ported. The slide is likewise ported as part of the factory compensation package. Sighting is via Glock fixed polymer sights with a white-dot front and white-outline rear.
Proofed in Austria, this pistol shows Austrian C.I.P. markings on the barrel hood. The frame molding includes the MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA. legend, reflecting its country of origin and import marking format.
Chambered in 10mm Auto, the G20C follows the standard 15-round magazine specification for the model while maintaining the full-size Gen 3 ergonomics and short-recoil, striker-fired operation.
