I just received two from Robert Johnson. They are 14rd (yes that's right, FOURTEEN round) flush-fit magazines for the CZ75B Compact and PCR, and they function perfectly. They have a slightly different indentation on the side of the mag body compared to my 13rd mag, and the follower has a subtley different shape, but the floorplate is identical. Also, the 14rd mags have three witness holes and actually say "14" next to the lowest hole. My 13rd mag has no text and only two witness holes. Springs seem a bit stronger on the 14rd mags too.
By the way, I paid $45 (shipped) per mag. I'm not sure how many he has left, but he also had some 16rd fullsize mags at $40 per mag.
Take care. Marko
