Compact mags will fit all of the "compact" CZ that are based on the 75B interchangeably.
Many of us use Pro-Mag (that ugly word) 75b Compact .40 mags in the 9mm guns, as they work fine, and hold 14 rounds of 9mm. (These are the ONLY Pro-Mags I recommend to folks, but they've done these mags right.) They won't work in the oldest compact CZs, however, as those guns have tighter mag wells.
I've never seen any true factory (14 or 13 round) Compact CZ mags on CDNN, and I check there all the time. All of us on the CZ Forum are constantly looking for them...
Full-size hi-caps will work in the compact guns, but won't fit flush. They'll stick out an extra 1/2" or so.
