I like guns and stuff a lot, so I caught a few of these too, like hand cannons and scout rifles. For hand cannons, I thought maybe since the cylinder comes out in a big chunk when you reload it, perhaps it's some fancy-dancey future tech where the hammer only has to hit the cylinder somewhere and it fires bullet mass from the barrel. Scout rifles, I'm still not sure how the magazine in that position works (unless the bullets are facing up and feed through the handgrip, but then it's need to do a goofy turn around the corner to be fired) but oh well haha I still enjoy the game so I'm willing to overlook em.
