I also suggest the Tueller drill. There is no better drill to demonstrate how little time you have in a self-defense situation.
You are reacting to some threat.
You are out of time.
You have to save your life right now.
Also consider that a holstered gun on your person is a safe gun. It can not fire unless you or someone does something. You know where it is, and that no child is messing with it.
