They say a grizzly can cover over 40 feet in one second. If you carry on an empty chamber you will not have time to chamber a round vs a grizzly at 40 feet let alone draw, and fire in that amount of time with one in the chamber.
Usain Bolt can cover approximately 30 feet in one second. If a person can run half that speed that's still 15 feet in one second. That is mighty slow at around 10mph approximately.
So a two legged bad guy can reach you easily in one second at 15-20 feet away. Most people can't even draw their firearm, and aim it that fast, then a little more time to fire.
Now factor in an empty chamber.
All this assumes you know you're going to have to draw, and fire. Factor in the time it takes for your mind to grasp the situation you are in, and it's going to add a little more time to the equation.
