Has anyone tried one of the new Russian made coach guns yet? I see that they are now offered with choke tubes. I also see that they can be had with a shotgun/rifle combination. 12/30/06, 12/308, 12/30-30, 12/45-70, 12/222 in side by side configuration. I handled of the first coach guns with the exposed hammers and the cylender bore and it looked like a pretty decent little shotgun. These new combo guns interest me but I am concerned about the sighting arrangement.
