How ever you mount it, I would go with an red-dot. I've used leupold, Nikon, Redfield, and Burris scopes on my revolvers for hunting. I switched to a Red-Dot about 10 yrs. ago and will never go back to a scope.
They are easier to learn to shoot with both eye's open and are plenty accurate enough to at least 100yds. If you learn to shoot with both eye's open, all you see is a red-dot on your target and drop the hammer.
I've taken a dozen deer with mine from 10yds. to over 100yds. Don't worry about batteries either, I turn mine on when I get to my hunting location, and turn it off when I leave. I carry a spare, but have never had to use it. Jerry
