The G20C's factory "C" configuration delivers a true compensated setup, with two barrel ports aligned to matching slide windows. This is a purpose-built, comped barrel and slide-cut arrangement direct from Glock, retaining the original design as shipped.
The Gen3 full-size frame provides finger grooves and an integral accessory rail, with a 10+1 capacity in 10mm Auto. Standard fixed polymer Glock sights are installed, with a white-dot front post and Glock rear notch.
Construction details include a steel, 4.6-inch barrel with polygonal rifling and a nitrocarburized slide finish. The pistol uses Glock's striker-fired, short-recoil, locked-breech system with integrated trigger safety, firing pin safety, and drop safety.
Markings and origin align with an Austrian-made Glock: "AUSTRIA" on the slide, an AT stamp on the barrel, "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." import marking, and "10mm Auto" on the barrel hood. This example is configured with the correct PI2059201 part number for the model.
