This is a police shotgun I have been modelling the past few days. :)
It isn't very detailed and it isn't textured(I suck at texturing) so you will have to do that yourself.
It is fairly low poly so it can be used in for example UDK, Unity or Blender's own game engine.
If you are using this model please post a link in the comments and tell me what you are doing with it. :)
I am not a professional artist, I'm just doing this for fun.
