So you are saying in lieu of actual deadly force?
Those pack a punch. It would suck. They can break ribs, knock the wind out, and etc… But if you brought a knife to a gunfight that would be regrettable. Especially in defending your family residence.

But I lean to the primal side when it comes to my family.
I’ve ran this in my head before. That was my final judgement.
