That's impressive skill, for sure. The only issue is it's under ideal conditions... nothing like a life or death fight where you may very well have been caught of guard, or off step, perhaps after being pushed to the ground, hit in the face, stabbed, slowed b/c you had to push your family out of the way, or the BG grabbed your wife instead of you, or there's already a gun in your face, or you're in your car, or getting out, or in, or loading groceries into the trunk, or out or any number of other things that will likely screw up your otherwise perfect draw.
Just sayin"
