Judge Dredd from the movies "Dredd" and "Dredd 3D", he uses mainly what I would think is a pistol. Now I haven't seen the movie, but I hopefully will soon. But seeing with the great action scenes I mainly watched, I think it would be interesting to see this weapon created. With switchable action options such as from this scene:

If switching doesn't work, maybe it could just be the original.
