Ran across this very short and sweet video this morning that spells it out very simply. Highest success with lowest risk. Only thing I’d add is, if hitting an innocent is not a concern for whatever reason, don’t be afraid to take follow up shots through the wall if you believe or know there’s another bad guy on the other side, i.e., someone obviously pausing at a doorway and you can see a foot or some part of them sticking out past the wall. I do believe that there are plenty of times I may grab a handgun instead of or before I grab a shotty, but it’s a given that a shotgun will generally stop the threat on the first hit. Camping with the shotgun and maintaining the element of surprise is our primary game plan. I am under no obligation to warn an intruder or give up my edge in my own home.
