fully loaded short barrel shot gun and GF on the phone calling 911. If BG in the house I hall wait in the defensive, once he enters the hall, lights gun and action! If multiple BG then they wouldn't dare enter the hallway to my bedroom after they saw there buddy guts get blasted.
-disadvantage to this is they shoot you through the walls of your house. (make sure you pump the first BG with 3 fast rounds blitzkrieg attack if not he may shoot you too)
Now if the BG isn't in your house but you hear unusual sounds at night outside, then let the dogs out listen for the barking and sneak towards it. Prior to investigating outside have GF or wife armed in the bedroom with phone AND IF SHE DOESN'T HEAR MY VOICE THEN SHE IS TO CALL 911.
K, so while outside if you can't ID the target sit and wait for their movement because you are setting them up for the ambush and your eyes are still adjusting to darkness. Once again Lights,gun and action you are the hero!
-disadvantage is a legal matter, you have to find a defense team that could prove you weren't just outside looking for somebody shoot like an alley bum.
