Hiya jinn707 and thanks for starting the thread. I'm sure Stu will come across the thread and chime in, or you can pm/call him to ask. That I'm aware of the batch of po-2's that czc had when I bought mine was bout it, and that was the fall of 2011. Recall a story about a military contract that didnt go thru made them avail to the public, but that could be incorrect.

Having the ambi decocker makes the most difference when shooting left handed, a sorely missed feature of a tuned po-1 I recently parted with.

And its actually easier to use grabbing both decockers at the same time to engage it.

And it took me a few different front and rear sight changes to find what works best for my use for the compact 9mm. Does have a ambi manual safety in the case, I know I'll never have any use for. I dont know if all the po-2s had the omega system trigger, this one does,and I preferred the action of the po-1 with a short reset added to it, but a short reset cant be done to this, and decocker/omega limits alot of what can be done to improve its action, or maybe change its action to closer to my ideal trigger.
What site has them?, I'd be interested to know, can you post the link?? What features of the po-2 got your attention? Be well.
