1. All guns are always loaded. Corollary: Even after you make sure it is not loaded, it is still loaded as far as anyone else is concerned. If you relinquish control of it, it is loaded again.
2. Never point the muzzle at anything you are not willing to shoot.
3. Keep your finger off of and away from the trigger until you are ready to fire.
4. Always be sure of your target and what is beyond it.
to those I might add:
5. Never handle a gun if you are impaired by drugs (legal or otherwise), alcohol, or emotional upset.
6. Store your firearms safely given the particulars of your own situation.
