Long story short I lucked onto a gun in a raffle two weeks ago. I decided to take the store credit and upgrade to a Springfield Saint. I am looking at some sort of scope or red dot for it. I have no experience with red dots scopes. I watched the Night of the Saint videos and and saw that they were using the Trijicon MRO red dots in it. Does anyone have any experience with it? I am also a little confused on the different heights of it. Any help would be appreciated.
