I own both, don't like shooting either one and haven't shot them in at least a year. I owned the 70 first and found the ergonomics awkward, the trigger insanely heavy and it was really easy to get my thumb webbing up over the beaver tail. When I got the 50, I was really hoping that it would somehow be better than the 70, but it was worse. I don't remember exactly why I thought that but I distinctly remember being disappointed. I love the idea of these guns, just not the execution.
