Just because you have a gun does not always mean you have an advantage. Practice, practice, practice, and keep practicing. You learn to take the safety off as you draw the gun. That is is you choose to have a gun with a safety. I don't carry a gun with a safety. The safety is having a proper holster and keeping your finger off the trigger until you are ready to fire.I'm not a gun owner so excuse my ignorance. I was always afraid I would shoot my dick off, can I assume the safety is on when you carry? How do you take the safety off and fire a shot with a gun pointed at your head? Always wondered about that. Note I am NOT anti-gun and not being critical of drivers who carry.
As for someone having a gun pointing at you, that is called drawing from the drop. You comply and you wait for your turn which almost always presents its self. Practicing gives you the confidence to make a quick draw, having a draw to first shot under 1 second is my goal.
