To counter my comment on Domino's weapon: Now _those_ are actual guns. I havn't seen a snail drum like that in years, they're horribly out of fashion... but that's a snail drum all right. Everything there is accurate. Even the fighting styles make reasonable amounts of sense, even if they're, ah, a bit exaggerated for comics.
It's like anatomy. Why did everyone stop drawing human anatomy in the 90s? Cars, guns, people, it's all the same.
