If you think about it, Chuck Norris probably carries a gun specifically to take it easy on bad guys who somehow earn mercy from him. A few bullets are nothing compared to his roundhouse kicks. He's sparing them from ultimate destruction!
I think he would carry one of those movie guns that never runs out of ammo.It would be full automatic and only shoot the bad guys guns out of their hands.And nobody would ever get hurt.
It doesn't matter what Chuck Norris carries...................
Jason Bourne will beat his ass with a ball point pen or a magazine and take it from him.
