What is a safe direction?

Do you know what a safe direction is? Of course it is the direction that if your handgun were to fire the bullet would not hit anything and damage or destroy it. How much time do you put into determining the safe direction? Do you know how far your bullet will travel? What if you are in your home, do you still practice this safety rule? If not you should! In fact you should treat your firearm as loaded until you have rendered it safe. You still need to keep it pointed in a safe direction.
