The Gen5 configuration brings practical upgrades. The Glock Marksman Barrel (4.02 in) uses enhanced polygonal rifling and an improved crown for precise, consistent performance. The frame deletes finger grooves and adds a slightly flared magwell for efficient reloads, while the reversible magazine release and ambidextrous slide stop levers support a wide range of shooters.
The MOS slide includes the optics interface with the cover plate installed, paired with front and rear slide serrations and a beveled front for efficient manipulation and holstering. The slide wears Glock’s nDLC finish in black for added surface hardness and corrosion resistance.
This compact 9mm Luger pistol offers a 10+1 capacity and Glock’s Safe Action system with three passive safeties. Sights are the Glock polymer post-and-notch set, with a white-dot front and standard polymer rear.
Origin and markings add clarity and authenticity: this example bears Austrian proof marks alongside the GLOCK, Inc., Smyrna, GA importer marking. The barrel, slide, and frame have matching serial numbers, and the accessory rail is Glock’s universal single slot for compatible attachments.
