I feel for anyone that's had a home invasion - I only hope that if I ever experience it that I can react swiftly and come out ahead. I've only had 1 break in and it happened when I wasn't home.
I did catch a guy coming up our back steps once, he said he was looking for a friend - :\ - Do not know if he was actually going to try a break in or not. I live on 2nd floor above an old bar, and we get a random crackhead looking for a place to smoke, or an alcoholic sleeping on the steps in the back sometimes. Sounds gnarlier than it is. I don't live in the ghetto, but we get a little spillover from time to time.
Glock 23 and a couple extended mags stowed between the headboard and the mattress, and an AK in between the bed and the wall if it ever gets extreme. If I go on vacation or travel for work I have multiple hiding spots - I break down all of my stuff and hide the parts. I just have field stripped stocks and receivers left in the safe. Come to my house, where you can find a K98 bolt in a box of Wheaties.
