Two center mass...the rest at the head if the first two have not stopped the attack. Assuming the attack means the perp is getting closer to you (otherwise it's not much of an attack) the heads shots should get progressively easier.
PRACTICE it! Two to the body, rest to the head...Just a mozambique that doesn't stop with the first shot to the head...which is how the mozambique should be anyway. Engage until the threat is eliminated.
