You don't shoot to break the shackle of the lock - you shoot to break the shackle OUT of the locking mechanism... and also to be dramatic.

Shooting two guns at the same time is objectively cool

Is it practical? Absolutely not.

A big enough surpressor combined with a subsonic bullet actually can make a gun movie-like whisper quiet, and even can be ultra quiet on a pistol.

But most of the ones used in movies are small enough, or used on a semiautomatic, to where they would be louder than portrayed.

So myth half busted!

On tracing a call: The call does not need to be actively going for the trace to work. As soon as it's made, the call can be traced, whether it's for 1 hours or 1 second.

That whole 2 guns at once part is misleading.

All it takes is years of practice combined with the willingness to lose accuracy per shot, or only doing it at close distances. It isn't some superhuman feat that the average person can't learn.

It just isn't useful compared to a single handgun in any practical situation. It's a show trick only, you'd never compete with it, and you'd definitely not want to try it in any kind of real world setting. The time you spent learning to do it would be better spent practicing any other handgun drills.

The shooting the lock thing is dependent on how much energy the bullet has. A pistol? It will probably not work. A rifle? It will likely destroy it.

MYTH: Spaceship doors can be opened by shooting the control panel with a blaster.

TRUTH: If the door is closed it can be opened by shooting the control panel with a blaster, HOWEVER....if the door is open it can also be closed by shooting the control panel with a blaster.

You've seen all the asteroid belts in the universe to know that they all have miles of vacuum?

Iron padlock?

I feel like the grenade one is true, like yea it will hurt but pulling the pin is not that hard.

A few nice movie references
