Tommy gun - low res - cylindrical shaped.

I made a Thompson Submachine Gun, but with a cylinerical shape instead of a box shape. I want to use it to run tests on a mobile device. I kept the texture resolution at 512px, while relying on polygons to smooth out the shape. There's a bullet in the chamber and it should be able to hold 20 bullets in the mag if you space them out correctly using two arrays side by side. The slide can move and the stock and front grip is separate objects.
