RE: SHTF gun??
at my apartment at school and in my vehicle: my new smith & wesson sw9ve in 9mm is within reach at all times. I also keep a couple of 30 rounders loaded up for my mini-14 in the closet should it come to that.
at home: my remington 870 in 12g with a tactical light and night sights. i also keep my browning buckmark 22 handy just in case. it might get replaced by the s&w soon. my mother doesn't like it, though. she's scared of handguns.
sucka sucka that step in my home...
