There's a reason to institute a 2-man patrol system instead of solo, so one can safely deploy the non-lethal solution, and be covered by his partner with lethal options at the ready. When you've to deal with hooligans who misinterpret privilege with entitlement, or understood his Bill of Rights too literally, or simply drunk/drugged to have any common sense, a mere baton not going to stop such belligerent subject, and without something like Taser to turn the subject into a shuddering blob of meat on the floor and be no more threat to anyone, the officer got only his service gun - in this case, a dingy pee-shooter that's not so effective in the non-lethal department, and definitely ineffective when comes to lethal force.
Worse still, in China where the tradition of "the size of the service gun at hand is proportionate to the amount of intimidation exerted upon the criminal class" lives on, it doesn't work in the law enforcement's favours.
Taser, despite its limitations, its ability to inflict memory-etching pain to those at the receiving end gives it the reputation, something that gives police officers an edge over the belligerent, but without the use of lethal option. Think about it, with Taser police can subdue a female belligerent from a distance, without her exploiting the chance to falsely accusing the officer molesting her.
So that's why the Type 05 revolver is nothing more than a good intention that's woefully executed, and that's the kindest way of putting it.
