Yep, either one works.
I have GRS on my 590 too. I've found that transitioning from target to target is very fast for me. I like them much better than a bead sight.
It won't take long to get used to it. Just remember it is not like using a rifle sight. You really dont even see the ring. just a shadow is the best way I can describe it. Very fast transition. I did get the new Aimpro with rail, I have a small holo green dot on it. I still hd to have the GRS. Never trust electronics without a backup.
I will post a review of the Aim Pro site and rail. Just installed it last night.
