I hope this conversation is about where to go to AFTER you shoot center of mass and the target doesnt go down = as in a bad guy with body armor
you always go for center of mass first
That is the assumption that I was under. You aim to stop the threat as quickly as possible, that means center of mass. Only
if that doesn't work should you intentionally target another part of the body. As a secondary target, the pelvic area is one of the best areas... But if the threat has a firearm my secondary target would be the head.
