The factory MOS slide comes pre-cut for popular red-dot footprints, offering quick optic integration without gunsmithing. Rear serrations and a matte nDLC coating provide confident manipulation and corrosion resistance in demanding conditions.
Glock’s Marksman Barrel features polygonal rifling and a target-style crown, designed to tighten group sizes while simplifying maintenance. At 4.49 inches, it delivers full-size sight radius and velocity for consistent 9mm performance.
An enlarged, reversible magazine release and ambidextrous slide stop lever accommodate both left- and right-handed shooters. The generous flared magwell speeds reloads, and the pistol retains Glock’s universal accessory rail for lights or lasers.
Fixed white-dot front and white U-notch rear sights offer a clear, snag-free sight picture, while the 17-round magazines give this full-size sidearm ample on-board capacity for defense, duty, or range work.
