Thanks once again for all the great advice.
Just a few clarifying points:
1) I'm all but test-driven on the subject of willingness to kill someone who enters my domicile with the intention of causing injury or death to me, my guitars, or whatever barfly happens to be passed out next to me.
2) Still haven't gotten around to getting my beautiful death machine, but I think I've narrowed her down to this sweet piece of tacti-black steel

3) Recently signed on to do my PhD in Econ, so it looks like 4-5 more years in less than hospitable territory. The plus side of this is I get a little extra cash (some of which will be going towards a folding stock and ghost ring for the soon-to-be-purchased black beauty) on account of a fellowship, so that means finally moving some place that'll let me have a dog (I don't have the room for a Tosa up here but I reckon anything that's a 60-80 pound ball of unconditional love, teeth and meaner-than-snake-spit growl ought do the trick).
4) Preempting this one: Yes, I know. Train dog to stay behind gun.
5) Recently got so shoot my buddy's 1911, AR15 and snub-nose .45. The AR15 was fun and all, but can't really see myself having it be my go-to gun for close quarters. The snub-nose is a straight murder weapon, but I'm not exactly trying to pull a Michael Corleone on anybody. Same goes for the 1911. Long story short, I tried the hand gun route (had been a while admittedly) and decided shotgun was my ticket.
I like the idea of having slugs/taser/rubber shells on the side, particularly the taser one (for no other reason than to get an awesome light show out of a terrible situation). Oh, and on a tactics note, 4 rooms plus one bathroom, all roughly10x12 feet, with a 5x2 foot corridor. Usually keep a light blocking blanket over the entrance to the living room (read: stadium style seating ghetto omniplex), and there's no entrance point other than the front door. The only time my place was broken in to, it was done through the back window in the kitchen. Just dumb kids, I figure, since they didn't take anything. So basically, anything being shot at at this juncture will be shot at very close range, since I have a tiny apartment.
Side note: A buddy (not the one with the 1911, etc.) decided to chime in on my quandry when he overheard me talking about it with a couple folks. His addition, "Couldn't you get like an ammo drum thing for a shotgun? Like that automatic one. You should see if they sell those."
No damnit, I don't think they sell A12's to the general public. But is he even at all, possibly, maybe right about the legality of having a drum-fed shotgun. I kind of feel stupid even second guessing my thought of "hell nah, that can't be legal" but it wouldn't be the first time I've felt stupid.
Crap, way over my page limit on this one.
Thanks again.
