No one has asked but just in case you were curious here is a wire...



... and smoothed...



The model is all quads except for a couple planar faces that I still have to dice up. I save that step for last just before I do the uv layouts.

This gun will not deform and so technically the planar ngons are fine; however, I know it causes several people here severe anal anguish to see ngons, so never fear they will be addressed in the end.
