I'd just add the PO1 has already been tested and proven to be good. The NATO tests were pretty extreme and demanding and the PO1 has that all under it's belt. That said, could you get a bad one? Sure anything made could just happen to be faulty. The PO7 is just the new kid on the block it might be great, it seemingly is designed (like the PO1) to serve you in the areas that seem to be important to you. Target, HD and carry. I don't think as yet, there are too many folks who have done a side by side as the PO7 pretty new. It's probably a fine gun but fact is it's very new, I've not seen any real reviews as yet. On the other hand, many are very fond of our Hakan (or other custom) grips and it does not seem to offer this option on the PO7. Everyone has different tastes, I think it looks cool and it does have a higher round capacity, it's just a choice you will have to make, I doubt that one is significantly more accurate than the other.
