The Gen5 MOS configuration delivers Glock’s latest feature set in a compact 9mm package. The slide has a factory MOS optic cut with Adapter Plate 02 installed, front and rear slide serrations, and an nDLC black finish on the major metal components. The 4.02-inch Glock Marksman Barrel provides the Gen5 barrel profile and rifling.
Targeted upgrades include an aftermarket red fiber-optic front sight paired with a plain black serrated rear for a high-contrast, uncluttered sight picture. An upgraded trigger shoe with an integrated safety tab is installed, an aftermarket hinged striker control device (SCD) backplate is installed, and an Apex Action Enhancement Kit for Gen5 Glocks is included but not installed. The frame wears an adhesive grit-texture grip wrap for added traction.
Controls and ergonomics are Gen5-standard: ambidextrous slide-stop levers, a reversible magazine catch, the Modular Backstrap System, and a subtly flared magwell to assist with reloads. The frame is polymer in black with an integral accessory rail.
This pistol is Austrian-marked, showing AUSTRIA slide markings, Austrian proof marks, and an AT barrel mark. It ships with three 15-round factory magazines, and the original parts are included, along with the complete GLOCK MOS Adapter-Set 01 nDLC.
