Interesting piece with a neat history.
This was originally a P2000 V3 contract pistol for the Saudi security services. However a falling out between the German government and the Saudis led to the contract being cancelled. The pistols were imported through a small distributor in Washington state. So having never been through HK USA, this is a bit of a collector's piece.
It has been modified to V0, which is not available from the factory in the US. Basically it's a V2 LEM, except with the decocker button on the back like the V3, which will put the trigger back in full double action mode. This is a nice feature for storing the weapon long term without the springs being under tension. Additionally, the hammer is spurred so it can be returned to LEM mode without racking the slide.
If you prefer a traditional DA/SA, you can get the parks from HKParts.net to accomplish this.
New XS Standard Dot night sights installed. However, the front sight ears down in the docetail were marred a bit during installation which does not affect functionality, it's purely cosmetic. Original sights included in case you want to put it back in its original status.
