As the thread in the lounge is talking about, we were discussing pros/cons of HD with a shotgun vs. a pistol. IMO, there is no answer. Every situation will have unique factors that will affect the choice. If I'm sweeping my apartment/house, I'm doing so with my GLOCK 27. If I'm barricading myself in my room and waiting for the police to arrive, shotgun's getting pointed at the door until the dispatcher over the phone tells me officer's are in the house and want me to unlock the door and I get a verbal confirmation. If there's rioting/looting and there are schmucks throwing molotov cocktails all over the place, and one of my SHTF buddies is with me, he'll be guarding the entrance with a shotgun and two sidearms, and I'm taking station in the window with my 4095, GLOCK, and 9mm pistol. Like I said, everything's relative, but in what I view as most likely (shattering of glass, burglar climbing in through window, I'm by myself), I'm going for my GLOCK 27 (arms reach, instant access), locking the door while remaining on guard, getting a shottie out of its case, and keeping that pointed at the door, GLOCK and spare mags on the floor so if I for some reason run out of shells I can grab that and not have to take the time to reload (I'm assuming if I'd fired the door was compromised and no longer secure). Nothing in my place outside my room thats worth risking getting myself potentially hurt or killed over. Now, if, say, I had the gf over and she somewhere else in the apartment when I heard the noise... grab the GLOCK, head into the corridor, find gf and tell her to high tail it into my room and then call the police while I cover her, and then join her in my room and barricade.
