When I learned to shoot back in the early 70's, I was taught to shoot at the pelvis since breaking the pelvic bone will put a man down while a shot or two to the chest, even the heart, can leave them standing and coming towards you for 30 seconds. Sure there are big gaps in the pelvic bone but the odds of hitting it are better than hitting a spine.
Not many teach this anymore and glad to see Mas teaching it to his classes. You may even hit something near and dear to the bad guy too.
