After mainy years searching i could not find wot font kingpin was using.
But with searching in the past i finded the old webpage www.urbangangsta.com
It was the introduction webpage of kingpin starting.
It also included a flash movie the same movie that was used in the screensaver of kingpin.
When i decompiled the flash movie i founded out that it was using the font:
Royal Pain so i downloaded that font and it was same font that kingpin is using.
So have fun with this font and type stuff in kingpin style :-p

How to use it, unzip the royalp.ttf in youre windows\fonts dir for example:
C:\Windows\Fonts\
or
c:\WINNT\Fonts\
And restart youre computer to make sure you can use the font in any program that you like.
