Hey, I was gonna say that....but I will defer, due to age and pecking order, and just say +1.

In all seriousness, remember the video was partly choreographed because both knew what was going to happen. It would all depend on the situation as to whether I tried to take the gun. If I truly felt that the end conclusion was going to be my death, regardless of my actions, then I would probably resort to a takeaway attempt....... and those in the video, if practiced repetitiously, looked like they had some merit if there was no other solution available.
A couple were pretty straightforward, but a couple also looked like they would most probably get you killed rather quickly.
YMMV
