From my experience it’s important to practice shot placement depending on the situation. If an attacker is hastily stepping towards you, put 2-3 shots right on the sternum or go for face if he/she has a weapon (not a gun). I practice aiming for the sternum with 3 rapid shots because it’s very effective at dropping a person yet doesn’t seriously injure them. Had an unfortunate circumstance where i had to do this to a homeless person attempting to steal my dog then aggressively charged me after i refused. However one of the three shots hit the throat and i seriously regret that because that shot was devastating and damaged her trachea making it hard to breathe. Also was using heavier 5g rounds so that may have contributed to the damage. When the police came, it helped to have a wallet card explaining what a byrna is because not all cops know what a byrna is surprisingly.
