P07 mags are shorter and a bit thicker/wider than CZ75 mags. Some have gotten CZ75 mags to fit/function in a P07 but it's not a secure fit and I wouldn't depend on it. P07 mags won't fit in a CZ75 at all.
I think in this case your best bet is to get the mags intended for the pistol in question. If you get a 75, MecGar are acknowledged to be among the best, and are luckily fairly inexpensive as well.
