What's a good home protection gun?

Never buy a gun to attempt to intimidate anyone.* That is the first Rule.* Shoot to Kill, that is the second Rule.* The best self-defense handgun is a 4 or 6 inch revolver in 357 Magnum caliber.* The best shotgun is a 12 gauge pump.* If you do not actually intend to kill anyone with either one, do not even think about owning any firearm.* Because that is a great way to end up being a Victim and Dead, rather than a Survivor and Alive.*
