If you are looking for a good carry gun, I'd recommend a pre-lock model 19. Pinned and recessed if your budget allows.
That would be my choice over all of those.
S&W stopped making pinned and recessed centerfire revolvers over four decades ago. There's nothing sacred about them. Same about the pre-lock guns. Ignore it if you don't want to use it. The current Model 19 Classic is probably more durable, and if the one American Rifleman tested is typical, it is extremely accurate. If an L-frame is too heavy, this (or the Model 66), might be a good choice.
For reference, here are the current weights and thicknesses of these revolvers (from the S&W site):
Model 19 Classic 4.25" (wood grips) - 37.4 oz., 1.45" thick.
Model 66 4.25 (rubber grips) - 36.9 oz., 1.45" thick.
Model 686+ 4.13" (rubber grips) - 39.2 oz., 1.55" thick.
P&R is for collectors. A new revolver shooter is probably better off getting a new gun, under warranty, than taking a chance on a used example, especially if you can check it out (and maybe even rent one), at a gunshop/range.
