I have been thinking about carrying a gun when riding. I have several revolvers and several 3rd Generation S&Ws. I think I would prefer to carry a SA when on horseback to reduce the chance of a 2nd shot being fired if the horse decided spook (I am working on that but I would always want to be safe). I have a nice 3rd generation 9mm and I was wondering if it was possible to convert it to be SA only? I expect I would have to have the hammer modified and I am not sure if that would be very practical - or what other problems would be generated. Has anyone ever thought about this or tried it?
