Good stuff dude !!
One thing and this has nothing to do with your stuff but a comment on "assassin" movies in general.
Why do they put professional assassins fighting like that?
I know that people like the flashy crap but with all practicality, a killer would NOT want to risk damaging his hands unless he had NO other resort and then he would probably try to fight more along the lines of the Bourne stuff and use as much open hands or hammerfists or elbows or improvised weapons as possible.
If you break a hand and can't pull a trigger....well...
Let me tell you, one of the things that used to drive my sniper instructors crazy was that I liked to fight.
I remember one saying that one broken hand and you are useless to us.
LOL !

Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
