With t he exception of the P-07, all the 9mm CZ-75s use what is basically the same magazine, kind of like 9mm Glocks.

Obviously, the shorter subcompact (RAMI) and compact (compact, P-01) magazines will not fit in the longer grips of the larger guns, but the longer mags will fit in the shorter guns. The SP-01 magazine is the same as the CZ-75/85 magazine, except it has a 3/8" thick plastic baseplate. It really only holds 18 rounds.

So the full size CZ-75s all take the same mags, the P-01, Compact, PCR all take the "compact" mags, and the subcompact RAMIs take the same mags.

The P-07 isn't really a CZ-75, despite the name. It uses a different lockup and is really a totally different design, but it uses "Omega" trigger components. The P-07 uses a magazine of it's own design.
