I have done the same thing. I have an Ithica Model 37 riot shotgun loaded w/ #4 buckshot near the bed. I also have a .357 mag close at hand. I live in NE Bernalillo county, NM where a 911 call is a waste of time.
Winchester mod 12 fans would argue that point but I'll stick by my statement, that Ithaca 37 with bottom ejection was a one of a kind pump gun. I'm not sure if Ithaca ever made a comeback or not. I seem to remember that it was sold to somebody after it was shut down the last time but I haven't heard anything else about it.
