Does anyone know how to upload that video at https://v.redd.it/c49nar79ep331 here?

I'm thinking of learning how to shoot guns, and want to know what went wrong.

It slipped through the top, but you're right, it could have gone much, much worse. My amateur prediction is that she wasn't gripping it tight enough, not even close since her hands barely moved while the shotgun slipped without struggle.

I'll add to the other person below. It's her grip and the grip shape of the firearm. The index finger isn't what I was initially worried about, it was her thumb. The index finger would get pushed back, but it would bend naturally out of the way. The thumb however would bend against natural motion and could easily dislocate or amputate it. The grip shape and how lightly she was holding it saved this from occurring as the firearm went up and then out following the grip shape.

Amazed that her thumb is unscathed

    $\begingroup$ Generally, this site isn't about debunking fake videos. This particular one isn't even related to engineering as it defies the laws of physics. Contact a local, qualified firearms instructor. Verify that safety is a principal component of their course, and then take a course with them. $\endgroup$

While she did not have a sufficient grip, the recoil was clear.

This recoil is the reaction force to the cartridge igniting to propel the charge (for every force, there is an equal and opposite reaction) acting in the line of the barrels, as seen the shotgun traveled initially in an approximate straight line. only deviated by the grip going through her hand.

  • $\begingroup$ Do a quick back of the napkin balance of forces. They very much don't add up in that video. And for bonus points, work through the rotational forces that would be involved. Definitely fake. $\endgroup$

  • $\begingroup$ @GlenH7 try firing a 12bore with the stock 1" off your shoulder and then come back to tell me about the reaction forces... $\endgroup$

Either fake, or the gun was held very loosely. Every gun kicks to some extent, shotguns more than most. It looks like the recoil simply pushed the gun through her limp fingers.
