Compare and contrast with westerns, or any movie with an arming montage. The boring answer is just that fantasy is about swords and westerns/crime dramas/action are about guns. "Why isn't historical fiction set in the future?" Well, some of them use that as a secret plot twist, but mostly it's just because anyone who writes about the future already has their own genre with better and more useful conventions. If you put guns in your fantasy then you're breaking a convention, which is fun and profitable in moderation, but you can only break so many conventions before you end up in another genre.
