Nothing beats a shotty for HD in an apartment complex. Although I wouldn't rely on the "shuck-shack" to do the job. Know how to use it.
I suspect most of the '9mm is for pussies' crowd is either trying to compensate for a small khack, spent to much time on the internet and not enough at the range, or both. Ammo technology has come a long way and Modern 9mm hollowpoint will absolutely get the job done with proper shot placement. Plus you can generally carry 50% more rounds per mag. Plus it's cheap. And before someone pulls that one (and only) ballistics study that gives the nod to .45acp, it's 20 years old, people. It's a different animal today. Yes, .45 makes a bigger hole and causes more damage but how much more and at what cost? I love the .45 cartridge, but where it has it's disadvantages, the 9mm shines. Don't be too quick to dismiss it.
