The 4.02 in Glock Marksman Barrel with polygonal rifling and a target-style crown is paired with Glock’s durable nDLC treatment on both barrel and slide. This finish is known for wear resistance and a uniform black appearance across metal components.
Gen5 frame and control updates include ambidextrous slide-stop levers, the removal of finger grooves, RTF texturing, and a subtle flared magwell for efficient magazine seating. An integrated accessory rail supports compatible lights or devices.
Sight picture is the familiar Glock setup: a white dot front and white U-outline rear. Front and rear cocking serrations on the slide aid manipulation from multiple grips while maintaining a clean, duty-style profile.
The compact .40 S&W format provides a 13+1 capacity using Glock’s factory magazines designed for the G23 platform. The pistol uses Glock’s striker-fired Safe Action system with a trigger safety, and the polymer frame and black finish keep weight and maintenance demands low.
Markings include MADE IN AUSTRIA and GLOCK, INC., SMYRNA, GA, AT. The overall package reflects the Gen5 design language and manufacturing origin that many Glock buyers seek.
