Ok, now I'm not very knowledgeable about guns, so correct me if I'm wrong. But would it not be a good idea, for the gun companies to make ammunition in calibers equal to a shotgun bore? Like, I know some pistols can fire.... .40 (I think) pistol ammunition and .410 shells. So, couldn't the companies make equivalent handgun and rifle sizes, so that you could have two options? Idk, I've always loved shotgun pistols, some of the old timey, pistol grip shotguins with a short ass barrel, oh yeah.
