Criminals just walk up and shoot you. Anyone that shoots realizes that you need to be 'Close', but not too close. And you need a reliable gun.
Chicago 'Hood-Rats' carry 22 revolvers. They get off 9 shoots and don't jam. They don't sit there and spend 2 seconds aiming, they just hit you anywhere, and then finish you off. A bank robber will go for capacity because he might wind up in a shoot-out. But self defense is normally 'close up and personal'
