Gun Disarm Yes or No?

Take a look at this short 1 minute video from Victor Marx and then comment with your thoughts on attempting to disarm an attacker.  

My personal take on this is to just simply give the attacker whatever they want. Usually they are just after your valuables and don't really want to risk jail time for murder.
However, should you decide to fight back there a few things happening here strategically. Number one, Mr. Marx is moving his head and shoulders "off the X" laterally as he reaches for the pistol. This is key! Chances are, you aren't going to be as fast as he is and the bandit will likely get at least one shot off. Obviously you don't want your head in line with that barrel if a shot goes off.
Second is that he's starting the gun grab from a "hands up" posture. Not only does it signify a defensive and submissive attitude, but it allows his hands to have to move a shorter distance. This is important to remember as action will always be faster than reaction. The faster he can get his hands on the gun, the less likely it is for the bandit to out-flinch him. There are a few other tactical tidbits here that I will forgo for now.

From a common sense approach, I'd like to point out a few things. First, this guy has practiced this gun disarm over and over for years. Literally making it the most often practiced drill in his arsenal.  I don't know that for certain, but you don't get this good at something without time and sacrifice. He's put a lot of time into it and has sacrificed practicing other skills in order to acquire the time to practice this one. Second, I would offer that the bandit could turn this gun grab into a wrestling match.  A close quarters retention fight for your sidearm is never a good plan, so if your disarm is successful, I recommend creating some serious distance as fast as you possibly can.

Again I just think it's a poor decision to attempt a disarm like this, but what are your thoughts? Let's discuss.
