Hey all. After being into Trigun for about two and a half years, I got thinking very early on about building those revolvers that Vash and Knives have, along with the arm-gun of Vash's. I've decided on a one-shot shotgun for the arm-gun, seeing as it could be flicked out, shot, and get rid of the baddie in a matter of about a second if you are slow. However, I'm having trouble with the revolvers, seeing as there is very little information on the inner workings of a revolver that fires from the bottom part of the barrel. I'm wondering if anyone has any like, ideas or drawings or schematics that they would have on such a thing (No, I don't mean pictures of a Mateba).
