The "where to aim" topic pops up often on gun & concealed carry forums.
I'd advise to aim "center mass" the largest deepest section of a human shape target. If, and I mean IF there is a chance the felon or bad guy does not go down(the threat stops), then I would advance to either a headshot or a lower torso/pelvic area shot.
Some untrained shooters or concealed carry license holders think the headshot is the best or first place to aim. I disagree. The human head is small & not very thick compared to the center mass of a torso.
Hollywood movies & cop shows are not training films.
