Product works well on arrival. doesn't fit out of the box with glock gen5 mos cuts. - Holosun HE509T Reflex Optical Red Dot Sight

The adapter plate that comes with the red dot does NOT work with Glock Gen5 MOS cuts, even with Glock's included RMR plate. The screws are too long and they don't fit the Holosun adapter plate to the Glock adapter plate correctly. I feel like if I'm paying almost $400, they should include an adapter plate that fits one of the most popular handguns out of the box, but what do I know. The functions of the HE509T work out of the box great, though. No errors that I can see, I haven't take it to shoot yet so idk how much it can take.
