Don't let him tie up, and if he shoots, ram your knee into his face and then if he's still driving, sprawl and hit him with tons of elbows to the brain stem or back of the head till it turns to mush gravy. Crossfacing someone with their head up on your hip is a great way to turn him off, if it's on the street and you want to use it, catch him right upside the nose, HARD, and do it over and over, with short choppy strikes with lots of followthrough.
