I forgot to mention that the scope mount is a double dovetail twist-in mount that was designed for the Smith and Wesson pistols. I cut a chanel in the bottom of it at a slight downward angle so it would straddle the rib and attached it with the three allen head screws that it came with. It is hellasiously strong but the scope must be removed to get it unmounted from the gun. It is a good setup if you are not needing to switch back and forth with the scope. Bob H.
