side of the actual torso. The arms won't BE at his sides, if he's a real threat to you. Also, arm hits are pretty usesless, unless you get lucky and shatter the bone of the guy's weapon-using arm. The 18" wide target is just for lames who CAN'T hit the 10" circle of the chest organs, to make them THINK that they are capable, of which they are really not. The FACT is, even at the ranges where you ARE capable of staying on the 6" HEAD, IN PRACTICE,with good light and ear and eye protection, you will PROBABLY miss the entire torso some of the time, when it's for real, and you will probably miss the chest more often than you hit it.
