Muzzle direction is the primary safety. Always has been and always will be.
–Bill Rogers of the elite Rogers Shooting School
“He told police he was oiling a handgun and had put a magazine in it and racked the slide when it fired, hitting his wife as she sat on a couch nearby.”
I absolutely despise the meme from Blackhawk Down that shows a trigger finger with the phrase “This is my safety.” Trigger finger discipline is a good thing but there’s a reason it’s Number 3 in the Four Rules of Gunhandling. Muzzle Direction is Number 2, as it should be in the scheme of things.
