**Update See Below**
Recently aquired a CZ75 Compact PCR. Searched for mags however I only came up with 17 round mags instead of the stock 15 round. I found this file browsing the internet but I cannot relocate it to give credit to the actual maker, so sorry.
His file was made for the P01, I altered it to fit the CZ75 PCR with this following 17 round mag:

The altered sleeve fits well and does not allow over insertion which could damaged the firearm. It is a little loose fit and at a later date I will adjust and test to give it more of a snug fit in the above mags. I have test fired multiple rounds through both of the mags I purchased using this sleeve without a single failure.
NOTE: if the slide is closed when inserting the mag with sleeve give it a slight smack to insert, with the slide open the mag seats normally with an audible click. When the slide is closed it still seats it just does not give that audible click and I am weird, I like to hear the click :)
Lastly: (Disclaimer) By downloading, printing, editing or otherwise, you take full responsibility of any damages or otherwise resulting in the use of this file. There are always slight differences in tolerances of printers and settings as well as magazines and hand guns that could result in non-fitment or improper fitment that could result in damage to your equipment. Please be advised.
Update 12-31-22
I have added a 2nd file: "CZ-Mag-Sleeve-Final"
This one is more snug fitting to the above mentioned mag and I added some rounding to the edges to help make it look not so squared and added a V-Notch to the area where the lanyard peg sits in case it happens to drift slightly left or right to help with mag insertion. I also removed a tad more from the thickness so the mag has just a little play like the stock mags. See added Pictures (Sleeve-1, 2 and 3)
NOTE: I have left the original file intact in case you prefer that design. (CZ-Mag-Sleeve)
