Russ - 9mm Luger and 9mm are the same round. 9mm Nato will also work just fine. 9mm +P will also function well. So just go to the store and get some "9 mil" and you'll be fine. The only one you really have to avoid is 9X18, or 9 mm Makarov. It is an entirely different chambering.

9mm Luger, parabellum, and NATO are the same. Do not use 9mm Makarov as it has different dimensions and will get stuck in the chamber. There are other 9mm rounds that won’t work but rounds like 9 x 25 Dillon won’t fit in you magazine anyways.

Russ, both are the same just different nomenclature. 9mm Parebellum, 9mm Luger, 9mm are all the same round.

yes you can 9mm goes by a few name 9 mm luger, 9mm, and 9mm parabellum are all the same 9 mm Nato is slightly hotter but will be fine in most guns including your CZ
