I can answer the question about the guns on Aim Inc. They're neither real nor concepts, they're for a game called Nationstates where you simulate your nation. The guy who did the art and the guy who did the design were part of a group of people, myself included, who were real hardcore into the game and did stuff down to ridiculous levels of detail. The 10mm caliber choice is actually my doing, since I was real vocal on our IRC channel about my love of 10mm Auto and it kind of spread.
