I think those unfamiliar with a proper condition 3 carry technique are unaware as to how fast into action it is.
I'm not familiar with how anyone else would do it, but with the Israeli system, there is room to keep a decent weapon retention position, and it can be done by someone well-trained (draw, cock, fire, scoring hit at 7 meters) in under one second. For someone who is slow and trains less consistently, this time is significantly higher; up around 1.5 -2.0 seconds. I believe this is on par with condition 1 draw times.
The way we do it in Israel, the cocking motion actually causes the handgun to be seated properly in the hand, forcing a proper combat grip at the time of firing. Further, since racking the slide is a gross motor skill, both experience and physiology bear out that one's ability to perform this action under stress is enhanced, not diminished. (We get better at performing gross motor funcitons under stress, while fine and complex motor skills become more difficult. This is physiological fact.)
Don't knock it till you've seen it.
