The scout rifles have always bothered me. I've been trying since day 1 to figure out how the magazines work in those things. The best I've come up with is "Advanced technology" and "Space magic". With the Handcannons, I just assumed they worked the same way a Mateba would. Most of these guns are fairly puzzling. It's really just easier to accept that it's some kind of mystical, new age, weapons engineering that we feeble humans don't yet comprehend.
