A shot with quality self defense ammo, or hell, even FMJ to th pelvic region is a pretty darn good fight stopper.
Some "old hands" passed that down to us in the big sandbox as a way of stopping a bad guy clean, keeping him around to interogate, and minimizing potential for over penetration. Good deal all around.
