Possible. The unmoving side is the key to whatever this is. One hesitation I have about it being AI generated is the slide stop shearing and flying off the gun. That's a minor, obscure detail AI would not have added. The blasts/flash... easily faked.
For the record... a Squib, also known as a wizard-born, was a non-magical person who was born to at least one magical parent. Squibs were, in essence, "wizard-born Muggles". They were rare and were looked upon with a degree of disdain by some witches and wizards, particularly pure-bloods. Muggle-born witches and wizards were believed to be descended from Squibs who married Muggles, introducing the potential for magical ability into the bloodline, thus a few generations later a wizard would be born to two Muggles.
I hope this clears things up.
