I have a 940 Mossburg with the Holosun 507k and can't get used to, #1 the dot with the circle around it. I wear glasses and it makes to much of a star burst on the target. #2 the way it sits so low down in the cut out. I figured I would love both of those. I have made a decision to put a truglo gobble dot pro on it so I can still be able to adjust the poi. Has anyone else had either of these problems with that particular setup or one like it? If so , do you have any recommendations that worked for you?
