Looks pretty nice, WolfeClaw. If it's your first model, you should be impressed! Looks like you have the flow of the gun down pretty good. Asteric mentioned a few things that are missing, and I would agree that a closer view or larger pic is in order! I think I can see some screws next to the trigger? Are they part of the texture, or are the separate meshes?
Anyway, the model is very nice for being such low poly. Throw a snazzy texture on there and you've got yourself a shotgun for a fun 2.5D shooter!
