The Gen 3 Mariner variant is identified by the laser-engraved MARINER marking on the right side of the slide, which denotes the inclusion of maritime spring cups. This example also carries the desirable USA slide marking, with the frame molded legend reading MADE IN USA – GLOCK, INC., SMYRNA, GA. The barrel hood displays Glock emblem and proof symbols.
Built on the Gen 3 frame, it has integral finger grooves with pebbled grip panels and no interchangeable backstraps. The dustcover incorporates a molded accessory rail, and controls are left-side-only, including the magazine release. The slide wears a matte black finish with rear-only serrations and no front serrations.
Chambered in 9mm Luger, the pistol uses a 4.02-inch steel barrel and Glock’s striker-fired Safe Action System. It accepts Glock double-stack 9mm magazines in the G19/G17 pattern, and this package includes three 17-round OEM magazines for a 17+1 capacity when using the included magazines.
Sighting is straightforward and durable: fixed polymer sights with a white-dot front and the standard Glock rear notch. The combination keeps the sight picture clear while maintaining the familiar Gen 3 Glock profile and handling characteristics.
