Royal Marechaussee Police Revolver

Revolver design for the police forces of Neo-Amsterdam. These guys (usually) shoot to kill. 

The idea is that the officer can click the laser switch button on the right, and the display would pop out of the side. The laser has a detector to see if a target is a human or robotic (as the robots tend to 'camouflage' themselves from time to time) and according to which one it is, the officer can switch ammo types to assess the threat accordingly.
