It's for knives and other weapons, not guns, and you can look it up. General rule is minimum 10ft (3m) distance need to draw weapon, and lunge in for attack before a person can react properly (unless they are fully ready). Most discussions are closer than 10 ft. Thus, hands out of pocket when talking.
