The G36 Gen3 Slimline delivers a true single-stack .45 Auto package with a 1.18-inch overall width, a 3.78-inch barrel, and a 6+1 capacity. Its slim profile and caliber make it a notable configuration within the Glock lineup.
This example features upgraded night sights: a Trijicon H3 15 tritium front sight paired with a steel tritium rear. The original factory fixed sights are included, giving the buyer both the enhanced low-light setup and the factory set.
The Gen3 frame includes finger grooves and standard Gen3 controls, with a left-side slide stop and a small square magazine release. It uses Glock's Safe Action system in a striker-fired configuration, combining a polymer frame with a steel barrel.
Markings and origin details include a Glock/AT proof mark on the barrel hood and a frame molding that reads 'MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA.' Matching serials are present on the slide, barrel hood, frame, and case label, and the pistol uses model-specific single-column magazines designed for the G36 platform.
