Griz is right on, the little J Frames are actually capable of stellar accuracy. Even with the tiny 1 7/8" barrel - the bullet grips the rifling in the first 1/3" as I recall. Accuracy is therefore as good as longer barrel revolvers (some say possibly better - the shorter barrel may flex less than a longer one). It's more mind over matter. Tight grip, front sight, squeeze trigger, release, repeat. Don't think about the recoil. There's more to it than that of course, but the little guns can do amazing things. I enjoy shooting 8" round steel plates at 15 or more yards. Last time I was out, rapid fire unsupported (1 shot / second) I was ringing those plates 4/5 - and I was having a so-so day. The trigger on mine is as smooth as a coil sprung action is probably going to be (I can feel the coils binding during the trigger squeeze a bit), the break is very crisp and the over travel is minimal. Sure, it's heavy, but if you don't have arthritis and you have decent strength in your trigger feeling, it's really no problem at all.
I don't carry my 642 as a primary often as I did 10 years ago out and about, but I feel fine when I do carry it as a primary - I just prefer something like my 3" 686. I do carry it around my house on lazy days very often, when just tooling around.
