No, it's not weird. How many people get taken by surprise while in the shower or toilet and somebody invades their home? Suddenly breaks in, rip off the tape, and now you're armed. No rushing for the guns, instant ranged defense.
My friend's grandfather keeps his Colt 1911 strapped to him at all times out on his farm, and he keeps a loaded .38 revolver in the work shed and bathroom counter in case somebody takes him or his wife by surprise.
EDITed to add: Up until I was six, my grandparents didn't lock their doors, but a double-barrel shotgun was next to the front door and my great-uncles Colt was in the closet next to the shoebox of money they kept on hand. They learned their lessons from the Depression. When they got lots of young grandchildren though, the doors got locked and the shotgun went into the closet, even though it was never loaded because it'd explode using modern shells.
