That would be my grandfather. He's an old-school guy and has always preached the virtue of the revolver for a self-defense gun over an automatic if the gun is going to be sitting fully loaded and ready to go. The revolver, unlike the fully-loaded auto is not under tension. The same thing goes with having a hammer-less shotgun sitting by the bed (unlike a double-barrel with hammers or a pump). It's generally a bad idea to leave guns under tension for extended periods of time in my understanding. Also, with a revolver, getting past a dud round is as easy as pulling the trigger again, whereas an auto requires more attention. You do, of course, sacrifice capacity, but if you don't solve a problem in your home with six rounds smartly spent, you're probably not going to solve it.
