Description
The Holosun 509PLT-MOS9MM is designed to allow you to attach the Holosun HE509T optic to Glock MOS slides without using multiple adapter plates. Install the 509PLT-MOS9MM adapter plate directly to your 9mm/.40 MOS slide using the provided screws and then attach your Holosun HE509T to the plate for a lower overall height.
