Okay, I'm going to show my "newness" to revolver ownership here but I just gotta ask.....How do Hogue grips attach to a Ruger Blackhawk? I'm in search of a nice set of grips to replace the factory "cheese graters" as I've seen the stock grips called in another thread. I want a little more to hang on to and like the look of what I've seen of the ones from Hogue but I can't figure out how they mount on the grip frame. I really don't want to modify the frame to mount grips.
