I picked up a 7 1/2" barreled Ruger Redhawk last year. I put a Leupold 2x M8 scope on it to try as I've never had a scope on a handgun before. I'm not sure I like it as much as I had hoped. I'm thinking of trying a red dot sight as an alternative but, I don't know anything about them. Does anyone make a decent, inexpensive red dot that could serve as a trial run?
