The Slimline MOS configuration uses a direct-mount RMSc-footprint interface without adapter plates, and this pistol arrives with a micro red dot already installed. The slide adds front and rear serrations for confident manipulation and wears a matte black finish to match the polymer frame.
Its 3.41" Glock Marksman Barrel features enhanced polygonal rifling and a crowned muzzle. This barrel setup is known for a clean, mirror-like bore surface and precise rifling geometry appropriate to Glock's design.
Controls are straightforward and duty-proven: striker-fired action with Glock's Safe Action system and a reversible magazine catch. The Slimline frame includes a single-slot accessory rail. Sights are fixed polymer with a white-dot front and a fixed polymer rear.
Made in the USA, this example bears the "USA" slide marking and "Made in USA, Glock, Inc., Smyrna, GA" frame marking. It ships with a 15-round magazine for a 15+1 loadout, plus two 10-round magazines for flexibility, and includes a Glock factory hard case and Kydex holster.
