HUTCH said it well- - -
(Pre-Ban) S&W M-13 or M-65 is just about supreme.
You have full magnum capability, and the extra inch or so of barrel gets a lot more out of the cartridge.
You have a noticibly lighter revolver than some mentioned, while keeping enough beef to handle a full 125 or 158-gr JHP magnum round. (Have you ever TRIED the five-shot snubs with full mag loads? I have.)
In my mind, the only real excuse for the small frame snubs is for pocket or ankle holster carry. If you must wear a belt holster, the three-inch is far easier to conceal than the two-inch. Has to do with there being some barrel to press against your hip and push the butt against your body. I know, sounds strange, but try it with a properly-designed holster, either inside waistband or outside.
Oh, yeah, the 2-1/4" M-19 or M-66: Why pay extra, in pruchase price, and inconvenience, and in wear and tear on your clothing, to have the adjustable sight? It is too large for pants pocket carry, while not holstering so well. It doesn't benefit as much from the magnum cartridge, and weighs more in the bargain.
Best,
Johnny
