The Slimline MOS configuration delivers a compact, easy-carry 9mm with a polymer frame, Rough Texture grip pattern, and an integrated beavertail for consistent hand placement. Front and rear slide serrations aid manipulation, and the factory white-dot front sight provides a clear reference.
The slide is cut for micro optics, and this pistol has a G43X/G48X micro-optic adapter plate installed. The Slimline MOS micro-optic footprint is RMSc-type, allowing low-profile micro sights compatible with this pattern.
Its 3.41 in Glock Marksman Barrel (GMB) uses Glock’s hexagonal rifling and is paired with a clean, mirror-finish bore. The barrel hood carries the Glock logo/proof, and the barrel lug is stamped "A1."
An aftermarket flat-faced trigger shoe is installed, offering a straight-profile contact surface. Markings include "AUSTRIA" on the slide and "MADE IN AUSTRIA GLOCK, INC., SMYRNA GA" on the frame. Matching serial numbers are present on the slide and frame plate.
The pistol ships with three magazines: one Shield Arms S15 Gen 3 15-round steel magazine and two Glock-marked 10-round Slimline polymer magazines, supporting a 15+1 configuration with the S15 mag.
