Correct. A prop gun wouldn't have the ability to fire a live round, the firing pin would be removed or the chamber/breech blocked to not allow a round to be entered (dependant on what weapon was used) they clearly had a live weapon on set, with a live round!
STOP CALLING IT A PROP GUN!
THEY DON'T SHOOT REAL BULLETS
