I think that I saw the film (isnīt the one that resembles 1984 from Orwell, where they do fight against emotions, etc.) and though I donīt think this art is a reality, I did like what I saw in the movie. He was using the guns in some martial art fashion, very attractive.
I am thinking now about the possibility of using a gun as a percussive weapon in short range, when the bad man has closed the gap to quick for me to load the weapon. And one can hit the BG with the weapon after taking it away from his hands on a gun disarming. Is an option secondary to shooting him for me, but is another choice, less lethal and better for Court.
If the gun disarm works, of course...
