I just handled nice older M36 and M60 for the first time today. I used to own a newer (mid-90's) model 640 .357 and until today, thought this J was pretty much the same size and weight as the older ones. I got rid of the 640 a while ago so maybe I don't recall correctly but it seemed that the older original j-frames made for .38 Spl are much smaller and lighter than the current ones designed to handle the magnums. (I know, "duh" on the cylinder length but it just felt smaller and lighter overall.) Am I nuts? I have been considering a 642/637 because I considered the 640 too big/heavy for pocket carry but these two seemed small and light enough to fit the bill for me. If I am correct about the size difference between the older and newer J's here's another question: Is a newer J-frame 637/642 the same size as a newer (magnum) jframe or the same size as the older 36/60 j frame?
