The G17L Gen5 MOS pairs a long slide with a 6.02 in barrel and a full-size frame, yielding a 9.53 in overall length. It is a striker-fired design with Glock's Safe Action system and internal safeties.
The Gen5 feature set includes an ambidextrous slide stop lever, frame without finger grooves, and a mildly flared magwell for efficient magazine changes. The slide has front and rear cocking serrations, and the durable nDLC black finish is applied to metal components.
The steel Glock Marksman Barrel features revised rifling and a recessed crown. Sighting is via a white-dot front and an adjustable polymer rear, providing a clear, factory sight picture.
This MOS-configured slide provides an optics mounting interface while retaining factory adjustable iron sights. Markings include "17L Gen5 AUSTRIA 9x19" on the slide and "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA" on the frame, with matching serial numbers on the barrel, slide, and frame. Glock OEM double-stack 9mm magazines are included.
