Your grandpa's 38 S & W revolver is probably about as reliable as handguns get. There's no way a semiauto is gonna match a revolver in reliablity. I have many of various types and enjoy shooting them all. But having to trust something for defense a revolver is still the best choice. Unless you're just into guns. And in most situations, I say most. If six shots ain't gonna get you out of trouble then..well ...you're in a bad spot. In these case's i'd prefer a short barrel shot gun and quick feet.. A short double barrel shot gun is still one of the most intimadating weapons to be on the wrong side of.
