Oh, one of my coworkers had a brush with death with a state highway Dept employee. The guy found a semi auto in a paper bag along the road and came over randomly pointing it at people and things. Coworker said be careful, that might be loaded so the guy drops the magazine and proceeds to go through the motion of pointing it at his own head and pulling the trigger.
Our guy snatches it out of his hand in mid arc and jacks the live round out of the chamber. The state guy just about shit himself. THERE ARE PEOPLE THAT STUPID!
BANG!
Now I drop the mag, rack slide back, lock it, and visually eye ball the ramp and chamber for the butt of the round, then look down the empty mag well through the ejection port, then release the slide, aim in safe direction, then pull the trigger, with the mag still out of the firearm, ONLY THEN I am convinced it is unloaded, until it leaves my hand.
