I keep mine simple for the time being. Loaded 9mm w/2 b/u mags on nightstand.
8 shot Winchester 1300 loaded with BB shot behind bedroom door.
Cell phone and maglight on nightstand. Motion sensor lights outside, wireless motion sensor chimes, one in front of house, one in rear.
Hinges on front and rear doors secured with 3" screws. On the jamb side, throw away striker plates that come with locksets and replace with a 1/8 flat bar 6 ft long and secured to jamb with 3" screws.
Windows at ground level have almost clear window film (tint) applied. Instead of glass breaking and falling out with one hit, it will take multiple hits to bust it thru..... more noise= more time for me to react.
