I think the burris 1.5-4 is a great choice. In my opinion, 4x is the top limit for a handgun and there is no need to go lower than 1.5x in a scope. A bigger factor with this scope is that it has a long eye relief and it can sit on the revolver such that it is 1-2 inches closer to your eye than most other scopes. it has to do with the geometry of the scope. Note the distance from the windage and elevation adjustments to the end of the scope nearest you. Compare this scope at arms length to others and you will see what I mean, especially at 4x power. When you compare two scopes side by side, line up there windage adjustment knobs, not the back end of the scope. At 4x power you lose a lot of eye relief in a EER scope, thus the eye relief aspects of this scope really come into play.
