Re: Gun safety poster?
According to Jeff 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.
Be sure of your target and what is beyond it.
—Jeff Cooper[1]
And according to the Canadian Government:
Assume every firearm is loaded.
Control the muzzle direction at all times.
Trigger finger off trigger and out of trigger guard.
See that the firearm is unloaded. PROVE it safe.
—Canadian Firearms Centre, The Four ACTS of Firearm Safety[3]
And sorry, I can't help with a poster. I had one of the latter's, for when I taught that course. Everything got 'disappeared' in the move. Ex's are bitches!
