Are we ever given any indication in-game that Rufus's weapon is a shotgun, other than it being double-barreled? Mostly because while I'm willing to believe that it's possible, if unlikely, to build enough strength to hold a shotgun steady and level with one hand, with no stock, but the recoil seems like a really fast way to seriously injure your wrist and/or arm. I didn't fire more than fifteen shells last weekend, several of which were from a smaller guage (20 - with shotguns, bigger numbers mean a smaller barrel diameter), and it killed to move my shoulder for three days afterwards. And...while I've never heard of it being done, it seems like it should be possible to made a rifle double-barreled, which would probably be lighter and have a lot less kick to it.

...Apparently the internet has read my mind. Just took a quick peek at the gun community on LJ, and someone was asking about the legality of double-barreled pistols. So it's definately possible. And yes, I am entirely guilty of overthinking fannish obsessions.
