I have seen a lot of answers, that are telling that it has more damage area and it fits in auto loaders better. I accept the second one, but not the first. Imagine a 9mm hits a vest and… nothing, probably a couple of broken bones, even though it has a larger damage area. Then the person takes their gun and shoots you. Your shots were probably useless. But if that 9mm was pointy it would, depending on the vest, penetrate it and hit the person, severely damaging the person. You’re now safe. That’s my scenario. So why are low caliber bullets not pointy?
In: Engineering
Solid lead slugs are shaped for aerodynamics not for penetration and low caliber rounds are less subject to aerodynamic forces. A tapered slug will not penetrate a vest any more than a blunt slug. Armor piercing rounds require some harder material, for example steel cores – and there is a low key attempt to diminish civilian access to armor piercing handgun ammunition in general.
