Bullets for self defense - SinterFire Special Duty 9mm Luger 100 Grain Hollow Point Frangible Brass Cased Pistol Ammunition

I think these are a great idea, just to prevent such extreme over-penetration alone. But the energy dump they pack, along with the fact that they will create multiple wound channels means more stopping power than traditional ball ammo. It hits and basically turns into shrapnel and for self defense, what more could you want.
