Can you toss up a pair of soda cans , draw from CCW and hit both in midair? it's not that tough, if you start with your hand in your front pants pocket, on the gun butt. :-) same tremendous advantage in a fight. Nobody pays any attention to the fact that your hands are in your pockets. Hitting a 2" mark at 1m is the same as hitting a 12" wide chest at 6m. If you cant do the first, you can't do the second,either. A man can charge 10 ft and be all over you in 1.0 second flat. Just ask George Z if stuff can't get way out of hand in less than a second!
if you have a timer, you can learn to react to the timer's beep, draw from hand in pocket, and hit the chest, at arm's length, in .55 second. Since .20 second of that was your reaction time, the actual draw and fire move took .35 second. you can punch him a lot faster, as in .10 second. you can take a step and punch him in .40 second, if you are well trained and fit. So, at hip shooting ranges, if there's just one attacker, you're better off to use hand to hand, IF you know how, and if you are a fit adult male. especially if your gun is in a hip rig, under a shirt. That position makes the ccw draw nearly twice as slow as the hand in pocket ccw draw.
