The Holosun Glock MOS 407K-507K adapter plate, reference KPLT-MOS9MM, allows you to mount Holosun 407K and 507K red dot sights on 9 mm Glock pistols with a standard MOS system. Its design adapts the K-series mounting footprint to this platform, providing a secure connection between the sight and the slide.

It is made of CNC-machined 7075-T6 aluminum, combining strength and lightness to provide a stable mounting base without adding unnecessary weight to the setup. It features a black hard-anodized finish that improves protection against wear and corrosion.

Its low-profile design keeps the sight close to the slide, reducing added height and preserving a compact setup. Precision machining promotes proper alignment and a stable sight mount, helping to maintain zero against recoil. A solution for expanding Glock MOS compatibility with the K-series compact optics.
