I was sort of scouting out my apartment to get a better sense of what is beyond each of my walls. My front door (and only realistic way in to my 3rd floor apartment) is adjacent to my only shared wall.
Basically my apartment sucks from a defensive standpoint, but hey, its a nice place to live
For now I will stick to some decent "non-trick" ammo for personal defense.
Thanks for all the great replies so far. I really appreciate this forum's knowledge and wisdom!
