Yeh, but the gun in your hand is a better choice, usually, than the one in the gun cabinet or even the next room.
Sure but we silly pilots were given a crappy 9mm and taught to shoot center-of-mass because of lack of penetration.
With a .22, I would think his training would have taught him center-of-mass, many shots, too.
(Not that I can say I would do any better under stress, either, but hey, I can comfortably second guess here looking out the window at skiers while sipping coffee.)
