Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on April 03, 2024

The Holosun HE509-RD Enclosed Solar Powered Red Dot Reflex Sight uses a proprietary footprint. Inside the box, the 509RD includes an adapter plate that will convert RMR cut slides to accept this optic.

Will this fit a CZ Shadow 2?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on March 30, 2023

The Holosun HE509-RD Enclosed Solar Powered Red Dot Reflex Sight will be compatible with a CZ Shadow 2. If you have an optic ready version, you will need to contact CZ directly and purchase their Shadow 2 RMR adapter plate. Once installed, you will use the adapter plate included with this optic to then mount the optic itself. If you do not have an optic ready Shadow 2, you will need to purchase and install the Evolution Gun Works Trijicon RMR Sight Mount (linked below), then install the adapter plate included with this optic, to then mount to optic itself.

Q
Starbuck, member, from CO, United States, asked on January 03, 2023

Will this work on m17?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on January 26, 2023

The Holosun HE509-RD Enclosed Solar Powered Red Dot Reflex Sight uses an RMR adapter plate to fit pistols with an RMR slide cut. The M17 uses a Deltapoint Pro slide cut and would not be compatible. You could potentially use a Deltapoint Pro to RMR adapter plate, but then that would mean you have to stack 2 separate adapters in order to mount the optic which would result in the optic sitting much higher than intended.

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on January 18, 2023

The Holosun HE509-RD Enclosed Solar Powered Red Dot Reflex Sight is designed to fit pistols with an RMR cut slide. If you do not have an MOS model Glock, you would need to purchase and install the Evolution Gun Works Trijicon RMR Sight Mount (linked below).

The Holosun HE509-RD Enclosed Solar Powered Red Dot Reflex Sight can be mounted to a picatinny rail. However, it would need to use a proprietary mount specifically designed for the 509T, or an RMR picatinny mount and use the RMR adapter plate included with the optic to mount the optic.

Will this fit a Sig XTEN?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on January 12, 2023

The Holosun HE509-RD Enclosed Solar Powered Red Dot Reflex Sight will be compatible with a P320 XTEN. Since the XTEN uses a dual cut slide for the Deltapoint and RMR footprint, the RMR adapter plate included with this optic would mount to your slide and would then allow you to install the optic to that plate.
