Situational awareness is a key part of a good self-defense mindset, but do you have your personal space limits calibrated correctly.
With a gun on your hip, you might feel like you can protect yourself from an attacker, but when should you move into a draw posture? Does that shady looking person 25 feet away constitute a threat?

Do you practice your quick-draw enough to meet such a threat?
This video from handgun instructor Tom McHale gives you a reality check when it comes to your quick-draw.
