- Never, ever load a firearm unless you are about to shoot a deer.
- Never climb a fence or gate with a loaded firearm.
- Don't spill your gin & tonic on your Perazzi.
Since then I have generally used the Four Rules a la Cooper
- All guns are always loaded.
- Never let the muzzle cover anything you are not willing to destroy.
- Keep your finger off the trigger until your sights are on the target and you are ready to shoot.
- Be sure of your target and what is beyond it.
