under stress, point shooting is either slower than sighted fire, or misses the chest a lot, beyond about 10 ft, with full size and wt,SA autopistols. With a DAO pocket pc, that's probably true at 6 ft, too. There's no reason to be without the sights, unless it's FASTER than using the sights. It's rather easy to prove that pointing is not faster than sighting, at 4 yds and further. An average of 5 tries, on the electronic shooting timer, with, say, a year's pay bet on the outcome (for some stress you see) and making the shooter pivot in order to fire (to get rid of bogus, pre-shooting "alignment" of the body on the target. Such will never be the reality of the situation. I fyou had time to get all "lined up" on the attacker, why haven't you already shot him, eh? Without a timer, and an average time, you are only guessing about what's what. Those with timers have known that I'm correct about this, for 20 years now. :-)
