How you appear to others can affect your safety.
No man (or woman) is an island, especially in a defensive encounter.
Knowing when to "trust your gut" is important when seconds matter and lives are on the line.
Your comfort level with your gun is readily apparent to everyone around you.
Making that first hit on-target is vitally important, no matter if it's in a competition or in defense of your life.
The easiest fight to win is the one that you walk away from, before anything starts up.
Having the ability to stay calm when trouble shows up takes time, effort and training.
There is no such thing as multi-tasking. Only one task at a time, done as quickly as possible.
Going to the range and pressing the trigger is only the beginning of armed self-defense. Creating a combat mindset requires no trigger time at all.
Keeping your head in the game is better for your safety than buying the latest gear.
