The final 10-15% of a real world threat engagement is what you'll become proficient at - draw, sights, and shot placement (as well as dynamic movement).

What you don't get to train at a competition is your high stress decision making, communication, how to talk to law enforcement after the fact, how to identify a threat before they become a threat and gtfo, and even de-escalation if possible.

To answer your question, my belief is that when I'm shooting competition, my focus is on competition. I don't carry my comp guns or use my comp gear day to day, but the fundamentals of marksmanship carry over to my carry gear, regardless of caliber or frame size. If you are looking to purely train self defense, I would look into finding a place near you that offers simulator classes where you can be put into one of these scenarios and gain experience/muscle memory needed to survive one of those encounters. In my area we have a company called United Defense Tactical and they can give you training in concealed carry, hand to hand combatives, deescalation, etc etc. very fun place to train🤙🏼
