The hunter is a fine hunting handgun, but if you do not want to change anything, you have to be choosey on your scope selection. The hunter comes from ruger with low mounts and not all scopes will fit between the fixed sights with the low mounts... i.e..
This is a burris 2x (nothing wrong with the scope), but notice it doesn't fit between the sights. I exchanged my rings with ruger for the extra-high mounts so I wouldn't have to remove the rear sight for it to fit. If you do that, any scope will work; if you do not want to change rings, be choosey with your scope.
