Great start, but one important detail; the holosight can't be mounted on the slide, since it would be flying around back and forth. Actually now that i think about it, you might want to make a charging handle/bolt system instead of the slide, since you couldn't shoulder the weapon. ^__^
Thanks for the input. I'll keep'em in mind since I like the design enough to do some further refinements.
Actually, on the Slide issue. The initial plans for the design (at the moment) was to make the Slide act as the cocking mechanism and not part of the ejection process; So that when firing, it doesn't move and it maintains a feel of familiarity.
