10 Times Movies Got Weapons Wrong

Near the end of the 1990s thriller True Lies, Jamie Lee Curtis' character fires an Uzi to help out her husband, who is being attacked by terrorists. She is so unprepared by the machine gun's kickback, she drops it down the stairs immediately after pulling the trigger. Luckily, the MG manages to fire off a few shots every time it hits a step, shooting every henchmen in the room dead.

It's an awesome and hilarious scene but scientifically impossible. Since 1968, gun regulations require thorough drop safety tests to prevent such a thing from ever happening. A semi-automatic has a firing-pin lock, meaning it cannot shoot while the firearm is at rest. Even if weapon is struck with great force, this safety mechanism will prevent it from firing. The only way to deactivate this lock is to pull the trigger.

There are incredibly rare instances when a dropped gun has fired but this is due to the weapon being poorly constructed. However, there is no possible way a gun could go off repeatedly after being dropped as is portrayed in this film.
