I may have to buy this figure just to laser scan the blaster and scale it up 4X to get a really good CAD file of the grip cover. Then scan the base weapon's grip and inverse it to get the back of the grip cover and viola! Ready for 3D printing.
I went poking around today and found this, cropped from a promo picture of the upcoming 1/6 Sideshow figure. Lame that the toy maker guys get references pictures and we don't. Not a lot of close view of the detail, but a very good profile for the basic shape, which I assume is fairly accurate.
If one gets desperate one could find pics of the Black Series blaster at Action Figure BBQ. Reasonably good looking for such a tiny thing!
