The Portable Psychology Diagnostic and Suppression System or the 45MW.TRG Dominator is the iconic handgun carried by enlisted Inspection and Enforcement officers. The gun is able to determine the identity of its holder, and requires authentication and wireless connection to the Sybil system in order to operate. Each individual gun can also only be heard by its holder.
When the Dominator is aimed at a target, it continuously reads and sends their psychological data (psycho-pass) to the Sybil system for calculation. When this value exceeds a certain level (indicating that the target is mentally unstable, and more likely to commit a violent crime), the gun will then be able to fire. If the level does not exceed fixed levels, the muzzle will not open and a safety device will be activated to prevent the user from pulling the gun's trigger. The gun is unable to work when it is not linked wireless to the Sybil system in most circumstances.
Before the gun fires, the muzzle opens up to reveal a complicated mechanism inside, part of which is used to read the suspects criminality. When the gun does fire, it lets out a bullet the color of sky blue. It is voiced by Noriko Hidaka. The gun has three modes: The Paralyser, Lethal Eliminator and Lethal Decomposer.
The Dominator's lowest enforcement mode, fires shots that paralyze the target. The gun does not need to transform for this mode. Used to capture suspects in order to safely bring them into custody. Often rendered ineffective when the target is under the influence of stimulants or other enhancing psychoactive drugs. This mode is only active when the Crime Co-Efficiant of the person is 100 or greater.
The standard lethal mode of the Dominator. When it changes to this state, the muzzle transforms into a larger form. Shots fired in this mode (or cybernetic body parts, in Senguji's case) will, upon contact, bloat up the surrounding tissue within seconds, causing it to explode. This is usually lethal (hence the name), although one can survive a shot to a limb, with severe injury. When the suspect is no longer in the gun's range of fire or is deceased, it goes back to normal. The Lethal Eliminator mode is only activated when the Crime Co-Efficiant of the person is 300 or greater. If the Dominator is in Lethal Eliminator mode, it may be switched to Non-Lethal Paralyser mode if injuring the target is not required.
The Dominator switches to this mode to eliminate non-living things, like drones. However, the Destroy Decomposer mode can also be used on living targets, as seen when Kagari was shot with it (although the Dominator exhibited unusual behavior, as its judgement system was overridden to switch into Destroy Decomposer). In this mode, the Dominator emits a massive discharge that causes disintegration on contact.
