The Slimline MOS system provides a factory optics cut sized for RMSc-footprint micro red dots, with the factory cover plate present but unsecured due to missing screws. Front and rear slide serrations aid manipulation, and the black-finished slide is matched to a durable polymer frame with a taller Slimline grip for improved control.
The 3.41 in Glock Marksman Barrel uses polygonal rifling and is designed for consistent accuracy and longevity. Fixed polymer sights are installed, with a white dot front and white-outline rear for a familiar Glock sight picture.
This example is customized with a silver flared aluminum magwell to speed reloads and a metal checkered magazine release that enhances purchase. The magazine catch is reversible, and the pistol uses a single-sided slide stop, consistent with Slimline models.
Capacity is 15+1 when paired with the included S15 steel magazines, and 10+1 with the OEM Glock magazines. Austrian-origin markings are present, including AUSTRIA on the slide, a Glock logo with an AT barrel stamp, and a circular proof/date mark.
