As stated earlier, it’s hard to beat a Smith model 13 with a 3” barrel. 65’s are nice also, but the blue just speaks! All business, and the last FBI issued revolver, it’s hard to argue with.
Beyond that, any of the L-frames, but one of the rare 7-shot 586 Smiths is a really nice revolver if you can find one. L-frame, 7 rounds, round butt and available with a 4 inch barrel. It’s a nice piece if you can stand the internal lock.
And, of course, the pre-80 Pythons.
Those are my top suggestions. Never had a chance to handle a Korth or Manuhrin, but I’d like to.
