At the beginning of 2015, Glock, the Austrian success-story weapons manufacturer, triumphed with the two pistol models G34 MOS in 9x19 and G41 MOS in .45 Auto, which enable mini reflex sights to be quickly and simply mounted directly on the slide.
Now they are offering the very popular Glock G17 in a service pistol format and the G19 in compact format in the MOS configuration. The two new models naturally conform to the Gen-4 generation, which has been on the market now for six years, with polymer-plastic grip with exchangeable backstraps, enlarged magazine release button and a surface structure with more grip.
The adapter plate in the 00 version only covers the window opening in the slide. This means that the slide contour and the familiar appearance of a Glock G17/19 with mechanical sight remain the same if the optical sight is not mounted.
The mounting plate in the 01 version is compatible with the reflex sights from Analytik Jena (Docter Sight-Models I to III), EOTech MRDS or Meopta MeoSight II and III.
The Trijicon RMR and the C-More RTS2, as well as the STS and STS2 can be mounted with the 02 und 03 adapter plates. The fourth mounting adapter is for the Leupold DeltaPoint and Leupold DeltaPoint Pro.
