Stun pistols are non-lethal weapons used by the police in Kiwi Blitz universe to subdue suspects. The stun pistol is capable of holding at least five rounds of stun bullets (possibly more) and can subdue most normal targets in one shot. However against targets with high cybernetic augmentation or genetically enhanced stamina they have proven to be ineffective.
The stun pistol has only been considered a mandatory sidearm for cops for three years since the beginning of Kiwi Blitz. Many members of the force felt they were ineffective as most criminals were not intimidated by a non-lethal gun but the higher ups in the police force made the stun pistol mandatory for all lower level officers.
