An old but ultra-reliable S&W 4586 with XS tritiums, my cell phone, a couple of SureFire lights, two extra mags of 230 gr. Gold Dots and an Emerson folder, all on my "General Quarters!" belt rig in the nightstand. Backed-up by a Remington 870 and 5 rds of #4 Buck in the mag (with +1 extension tube, chamber empty) in a rack mounted on the inside of my closet door.
Put the rig together after reading one of "John Connor's" columns in AH. Made perfect sense to me, as where exactly does one temporarily park his weapon or light while trying to dial "911" or anything else that might become urgently necessary with one or both of his hands while wearing only pajama bottoms, skivvies or if caught "going Commando" when the klaxon sounds? Actually try just sticking your pistol in the waistband of your shorts or PJs sometime and see what happens. It might be best to do this while alone, if you're shy.
