mete,
Did you read the part about the guy being listed in critical condition? That means that his life is still in danger and he very well could die. Did that one shot from the .40 S&W end the fight? That is the more important question to ask. We shoot to stop, not to kill.
The story is also lacking in information. While it says that the man was shot in the face, it did not specify what part of the face he was strunk and what the angle of bullet was. While getting shot in the jaw would be painful as hell, it is not necesarily life threatening. If the shot passed through his cheeks, it would also fail to be a deadly shot. Thw .40 S&W has plenty of power to penetrate the skull provided that the angle the skull is struck at is relatively flat. Deflection is still possible at sharp angles, but the shot will still cause injury and possibly reduce that person's ability to fight.
While there are no such thing as guaranteed one stop shots (maybe the .50 BMG at point blank range) most of us can only carry handguns. The most important thing is to keep shooting until the threat is neutralized.
