For CCW it seems a 38 special is barely "enough", and 357 magnum is painful to shoot. Both of those rounds are VERY old. Why aren't there better alternatives? A shorter cartridge would mean a shorter/lighter cylinder, which means you could have a 1/8" or 1/4" longer barrel without making the gun longer. What about 357 Sig or 45 Glock or a new cartridge with better numbers than a 38 but less recoil than a 357 mag? 9mm revolvers are rare, I've never actually seen one. True you loose velocity with a 2" barrel but it's still faster than a 38.
