I don't have a picture, but my brother owns a PO2 which he bought new at least 15 years ago. All I think I remember about it is that it is alloy framed with a rail and an omega trigger, and not a decocker. I think the designation PO2 was dropped not long after he acquired it which makes me think that it may be worth a bit more than a current PO1 with the same setup.
Original roll mark for the P01 Omega.
I see them from time to time. Usually listed a little higher than the p01 omega but a hard sell as it’s only a rollmark change.
Here’s a gem.
