CZ has changed the mags from their P-07 configuration to their P-10C. The P-10C mags (On the right) work in a P-07. I have 5 or 6(I've found 5 but I think I have 6) of the P-07 mags (on the left) that I'd like to get 3 cuts in to make them work on a P-10C. I'd prefer local in Portland/Salem area. But I could ship. There used to be a company that did these for $10 each. But they stopped.
