Check out the Internet Movie Firearms Database for Black Lagoon. Fuck yes. Now someone who knows about guns needs to write the Saiyuki article.
Also, has anyone found any canon heights for the Lagoon crew? I'm sorely tempted to just give Chang a height (as Chow Yun-Fat is 6'1" and all) and go from there but they don't conveniently stand shoulder-to-shoulder much.
