What do you think of the Holosun 507c PMO?

I have a Trijcon RMR-2 mounted on my STI Staccato P DUO and love it.

Using a red dot sight on a pistol is a game changer for me! I wear reading glasses, but don't need them to accurately pistol shoot with the optic.

I have the 510c Elite. It has the green dot/circle. Similar to what you are looking at. It works very well. Never have to adjust anything once set, just pick it up and go.
