Do not use frangibles for self defense
They create ugly surface wounds and thats about it. Some goblin trying to get you to room temp is probably not going to notice being hit by one. Adreneline is a natural pain killer.
Always use appropriate sd ammo. I prefer hornady critical duty or defense

The problem with being stupid is you cannot simply decide to stop doing dumb things...
