That's after half an hour's work last nigt - now I'm doing half an hour more. The changes were basically the addition of a hole for shooting out cases, a trigger, and a better shape for the handle. 680 triangles at this stage. Expect another post soon...

EDIT
Here's the *final* mesh. If you want me to flatten the bottom of the handle a little for a clip, I can do that. For now, I'll start unwrapping and texturing.

You can't see it from that angle, but I scaled down the barrel a little bit.
