But none of the guns in most of the animes are fictional. There might be one here and there but the same thing apply to guns like Hellboy's Samaritan. It isn't a real gun, but might have been based on one.
I also have a problem with some of the guns posted in anime that aren't real or based on anything real, but since we don't have a don't post fictional weapons if they are not real, people do it anyway.
I mean, if a gun looks like this:
It's fine, because it's a real gun.
