I use that exact gun 7 1/2" barrel. I have 2x scope that is not expensive but I would never recommend a cheap scope. It groups nicely with a rest. I don't want to be a cowboy with it so I keep it for under 50 yards and in for deer. Yes it's capable farther than that but it drops significantly. 50 yards or under they will drop as fast as they do with a rifle. It is a fun gun to shoot. I had my trigger done at 3 pounds of pull. Made a huge difference in accuracy. I love Ruger revolvers and they IMO are one of the best made handguns.
