I put maybe 1000 rounds through a 3" M65 Ladysmith I bought "for my wife". .38+P 158s were fine, 180gr .357s pretty stiff. I often carry a 3" M63 around, and the extra inch makes a big difference in usability compared to the snubbie 1 7/8" models. I think an M60, using good +P .38s or handloaded .357 equivalents would be about ideal for a carry revolver. Still, there's a lot to be said for the various compact 9s available now too, one being price. Good revolvers are pricey.
I highly recommend the Simply Rugged Silver Dollar Pancake holster for 3" J-frames. Gives you several options: IWB, OWB, strong-side or crossdraw, even Tanker-style with the optional straps. The 3" guns are a bit much for pocket carry.
