The PO1 and the Canik C-100 seem to be very similar in appearance and in that they each have the alloy frame.
I already own the C-100 and it is a very nice pistol. Only about 500 rounds through it so far.
Is there any advantage to the PO1, other than the CZ name, to the point that I would want to replace it with a P01? By the way, I love my CZ 85b.
