My thoughts on the use of this is simple.. If a perp comes into the house and I am there.. The 45 is just fine. I can hit him from accross the room.. But if someone comes in and I am not in the house.. I am not sure my wife will be able to hit them with a single bullet.. Chances are she will be extremely scared.. So I told her.. first 2 shots to the face with either #4 then follow up with 3 45's to finish em off..
