It is a load by S&B in the Czech Republic for the Slovak police (hence the PZ) there is also a load with headstamp PS P 9x19 Z. I will post the box label when I have more time!
The load is only known in the 2004 date illustrated. Nice item!
Thanks for your help.
Here is the box label for your Czech cartridge to confirm the S&B manfuacture.
