Me and my fiance keep three guns beside our bed, but leave the magazines out. Only one has an actual bullet in the chamber and it's on my side, just as an emergency precaution.. I don't necessarily recommend it though because it is dangerous, and an accident could mean a life of regret and in jail.
On another note, if you plan on buying purchasing more than one gun and want to make it easier when grabbing the right clip, buy a rifle and pistol in a caliber with interchangeable mags.. I suggest .40 S&W, but that's just me.
