The 16 German States are resposible for their police forces. "Police" is generally a state "business."
The "Bundespolizei" was formed a few years ago from the Borderpatrol and the Federal Transportation Police.
The Feds and the States agreed on one unified "code" (set of rules regarding the guns and ammo of their police).
Since the late 1970s, German Police uses 9mm. Around the year 2000, they changed from FMJ to Semi-jacketed bullets. It's called the "Polizei Einsatz Patrone" ("PEP") -- rougly translated "Police Action Cartridge"
Although, it is in german, here are the technical specificatios:

Metallwerk Elisenhütte GmbH Nassau (MEN) was the first company to offer the new cartridge a few yeras ago.
The Bundespolizei (and German Customs Service) are currently procurring the HK P30.
The state police forces have also been getting new pistols over the last years. In my home state, they have the Walther P99 in DAO, other states have the HK P2000 and the P30. The HK P7 is also still in use, as is the Walther P5. The Sig P6 (P225) was also wildly popular with some forces. But they are withdrawn from service.
Glocks are deemed to be "unsafe" for german police, so the regular police does not have them.
German police officers are also trained on sub-machine guns. The MP 5 has been the model of choice since the 1970s, some MP 7 are also around.
The hand guns are considered for self-defense purposes. If the police wants to go on the offense, the sub-machine guns appear.
The dutch government has recently decided to buy a special version of the Sig P250 for its police departments. They also decided on a special police cartridge with 95 or 98 grains
