Jet Li Gun Disarm

How realistic is it to disarm someone pointing a Beretta 92FS pistol at you? You can see this in one of Jet Li’s movie, “Lethal Weapon 4”.

Jet Li does it by removing the slide off in real-time.
Youtuber Ian McCallom examines how this is possible.
The basics is that you need to push the side button in and rotating the disasembly lever down, then the slide can be pulled away from the lower.

Ian performs this disarm and is surprise that its not as hard as it seems with one hand. However, putting this into a real-time stress related scenario with a resisting partner would probably produce a null. Not possible.
So please don’t try this at home with a loaded pistol.
When it comes to fancy gun disarm leave it to Hollywood to entertain you. For real disarm stick to something like this.
