A nice combo would be an earlier K22, or Model 17 (same thing), paired with a Model 19 in .357 (.38 special). You could go either 4" barrels, or 6" barrels. Generally, with the K22 4" a Model 18 is easier to find. Also, I would want the Model 19 with the target hammer and trigger.
I love S&W revolvers. They are the Mercedes of revolvers. I have a gun safe with 60 revolvers in it. Narrowing it down to only one, I would have to say my K22 Outdoorsman, from 1931, and it was #182 that was shipped. Quiet, accurate, and practically like a hand made revolver. I love showing...
