Take down- Get out of the path of the bullet. Isolate and neutralize the weapon Neutralize the opponent. The rest is all style.--Believe it or not, this is almost all Aikido, though he's using some force, since his attacker has little momentum.
[Take note: this is how to properly disarm someone. Always go to the outside of the arm, not the inside. ah yes I have been doing it wrong the whole time it seems cowering in fear was not the first step]
