Glock G17 Gen5 MOS FS 9mm Luger, Austrian-Made, GMB Barrel, nDLC Slide, 17+1, 3 Mags, Case
This Glock G17 Gen5 MOS Front Serrations (FS) 9mm stands out as an Austrian-made, full-size Gen5 with matching serial numbers on the slide, barrel, and frame. It features the Glock Marksman Barrel with an improved crown and revised rifling, a black nDLC-finished slide with front and rear serrations, and an MOS optic cut with the mounting plate installed. The pistol also includes ambidextrous slide-stop levers, a flared magwell, and a reversible magazine catch.
Notable markings include CIP-style proofs and the GLOCK AT barrel stamp. This configuration has reportedly been discontinued for commercial sale and superseded in the lineup by the G47 MOS, adding context for buyers seeking this specific Gen5 G17 MOS FS setup.
