Any of the CZ 75 magazines will work in the CZ P-07. ProMag magazines will probably work, but they're not the highest quality magazine. I would get some MecGar magazines instead. I think they're as good as the CZ magazines.
Cheaper though to by mecgar than cz right?
I had good luck with 1911 mags at the range from promag, but they sucked with hollow points. just a target mag.
