Getting shot really messes up your response. Similar reaction was seen of the Indian jeweler video mentioned in one of the posts above.
It’s why the FBI study of perps who shot or killed cops practiced to get first shot out as quickly as possible, a shot on non-critical area, even the noise made by a missed shot, produces tactical and psychological advantage.
Another possibility is injured hand: if one of your hand is injured it makes chambering difficult if not entirely impossible. There was a thread on Arfcom, that the good guy was having trouble getting shots off his 1911 because his hand was shot by perp and he couldn’t squeeze the gun hard enough to disengage the grip safety.
Yeah, in training, we talk a LOT about breaking OODA loops. ANYTHING, and I mean ANYTHING, that makes someone stop and think is a good thing if you are behind the power curve.
Train so you skip steps in your OODA loop. If you are skipping steps and bad guy is constantly restarting his, you can catch up and get ahead.
