With that logic, might as well carry a 22LR. No one wants to get shot with one of those right? Or forget the gun and carry a knife.
You are correct. I doubt anyone wants to get shot by a .22 or a .17 or a .40 etc etc. (Or stuck with a knife) What does all this have to do with the .380 vs 9mm question? The .380 ammo I carry meets FBI penetration standards. I'm good with that.
