Pretty much as others have said before me. Although there were & are ‘other’ relatively obscure / obsolete 9mm variants, the one one that maintains any relevance in today’s World would be the 9x21, IIRC. That ctg was developed to bypass Italian Law which does not allow any civilians to possess any caliber currently in Italian Military use. Other Countries also have similar mandates, hence the reason for, & popularity of a few certain cartridges, such as the aforementioned 9x21, .38 Super primarily in Mexico & elsewhere, 7.65mm Luger is yet another which found its way into Sig-Sauer P.220’s during the 1970’s +. Remember, when the average folks are denied use of something, they tend to strive for a way to circumvent it !! Soooo, your CZ should work just fine with the .380 ACP, aka 9mm Kurtz / Corto. Personally, I would use the weakest load available.
