Right now, I carry a Kel-Tec PF9. The recoil has never bothered me, but my Dad had severe wrist pain when he shot it. He only got 2 rounds through and had to quit. I've been experiencing more pain in my fingers and some in my wrists, but not to the point where I cannot shoot. It may well be coming. I know there is a shotgun that has no recoil (forgotten the name, it is also fully auto). I'm not an engineer, but is it the case that pistols are simply too small to develop that kind of engineering (low or no recoil)?
