My very first CCW back in 1979 was a 2" RB M10. Regrettably I sold it and bought a 2" M60 instead. While I do prefer the size of a J Frame for EDC, the M10 handled stiff loads much better. I always though that for a EDC/CCW the J frame suited my need better and that the 3" barreled version of a M10, M65 and alike is a better option than the 2". I also always thought the 2" M10 looked a bit funny - not that it really matters much. The 3" version is much better balanced IMO.
