SOLVED. Space Opera Comedy YA - Bionic Space cop, spent bullet quota. [s]

[The Elusive]

Self answer: Zack Galaxy by Jordi Sierra i Fabra. Which is an Spanish author, and thus searching for it in English was not the best way to find it.
May not be 100% accurate and out of order. I read it in Spanish. Maybe ten to seven years ago.
A space policeman is woken up by a call from his boss, which chastises him. He complains that he must use a pistol while the criminals are greater in number and have automatic weapons.
The boss rebukes, and tells him he has spent his yearly bullets quota.
We are given a percentage of how much of him is bionic (I think it's 46%), and details (his spine has many discs replaced with a combination of metal or ceramic and plastic, he has a cow organ (hearth? lung?), a mechanical arm, ...
He is sent to a space station (to investigate a disapparition?), supposedly an easy job: Ask some questions, ... to get him out out the way so he doesn’t ruin his boss chance of promotion.
Also, I think his mother calls him after the boss, or maybe the boss call interrupted one from his mother, which wants nieces.
The space station main business is gambling. He passes by a gun shop and thinks about buying some bullets, but discards the idea as his boss told him to stay out of trouble and would probably find out.
It turns out the space station ruler is an "old fat woman" or the like, which eats lots of chocolate candy, and a criminal which got scot-free due to lack of evidence.
She acts friendly, and gives the protagonist some free credit on the casino. The protagonist sees through the act, but behaves like he has been fooled to avoid suspicion. The dealer is a cute girl. He chats with her, and her shifts ends. She ask him to follow her to his place. When they arrive, she goes to the kitchen or something like that. The protagonist can't believe his luck. Of course, it's a trap! How could he have fallen for something so obvious? Then he is shot a dart. A tranquilizer one. And two thugs are carrying him to the waste disposal facilities. Which will send him to space. He manages to scape (aided by the girl, which is remorseful?).
He goes into an open spaceship, which turns out to be a pirate one. (The pirates are latter shown to be doing business with the antagonist woman).
He flees the spaceship, I believe aided by by a prisoner (which may or may not be human) of the pirates, using a teleporting device banned by the law due to it's tendency to fail catastrophically. He finds out his pinkies have switched places, (Remember than one of them is bionic) and/or with his new ally. Or maybe he switched something else with his companion. The planet he is in is a natural reserve. He is explained this by his companion, and that the pirates captured the animals and sold them, thus explaining why they where teleported there. Somehow they return to the space station, the protagonist accidentally triggers self-destruct, and he seems to be f**ked when due to some hidden mic trickery he gets a confession from the evil woman and he winds up a hero, and most importantly, not fired.
