Excellent, reality-based firearms training — taken before you need it, in hopes you never do — can prepare you to take care of yourself emotionally after a deadly force encounter.
1 – Good training helps you make smart choices. Smart choices mean better outcomes and fewer regrets.
2 – Good training helps you know what’s possible and (perhaps more important) what’s not possible with the gun you actually carry, given the skills you actually have. This leads to less self-blame when the ending isn’t as ideal as you’d like.
3 – Good training helps you understand, in advance, what types of emotional and psychological responses are “normal” after a rare and abnormal event… thus neatly dodging the “Am I going crazy?” complication.
It’s really a form of self care.
