I use the grip with my Universal with a 6X9 back, but others prefer to shoot sans grip, feeling that they are able to hold as well or better than with a grip. I think the back is rugged, little chance of breaking it by holding it. Cleaning is straight forward, but be careful cleaning the rang finder, you can jostle the prism and put it out of alignment. My Universal is due for a good cleaning and adjustment, I need to find someone who still works on them, I don't think we have a tech in the Phoenix area who works on the beasts.
