In this video, which has been viewed fifteen million times on Facebook, John Paul Terry shows some common defense techniques against a gun.

Please note that these techniques are only demonstrations. Defense against an armed attack is dangerous and a positive outcome is not guaranteed.

John explains that the first defense is simply attacking the hand of your opponent to put the barrel of the gun away from you. He does this by reaching out with the same side hand and pushing the gun away from you while at the same point moving your body away as well. This will take you out the immediate danger of having a gun pointed at your chest.

From this position, John suggest a quick strike with your free hand to the throat of your opponent as you are doing this. You should do this as you are attacking the hand and moving away to give the attacker the least amount of time possible to respond. At his point, you can disarm him and if necessary deliver an additional groin strike.

Also another important fact John points out that while disarming the gun, it should be done in such a way that the muzzle points back at the opponent, not at you. This can be accomplished by holding strong on the barrel of the weapon and using your other hand to come under the butt of the gun and pull it underneath.

John also points out the importance of misdirection, that is making your assailant believe you are complying before counter attacking. This can be as simple as putting your hands in the way.

Next John shows a second technique to take the gun away from your assailant immediately by attacking the gun with both hands. He also shows a variant of the technique with the weapon pointed directly at your head.
