I'm not going to hear suspicious noises coming from my living room. My dog is going to go ballistic when he hears anything anywhere near the house. When I check on odd things, I carry a 380 semi-automatic and 3 extra magazines. If and when I feel I need more firepower, I'll go back and get my Carbine and 3 extra magazines. When I go to get the carbine, I'll also dial 911 and tell them to send help and not to shoot the crazy guy with the carbine.
