I was watching Pawn Stars(not the greatest source for information on anything, I know) and there was a sequence where the guys went trap shooting. rick pointed out that the others were using home defense shotguns, while his shotgun was made for trap shooting. I wouldn't have known it mattered, but his drastic superiority in the competition seemed to validate his claim. I know nothing about shotguns, so first of all, is it true that certain shotguns function better for trap shooting, and second, why is that, and what about the guns makes them different?
