Hardly an expert on the Israeli models but the first step would to find out how old it is.
IIRC if its 1992 or earlier its likely a "pre-b" gun and will need the older style mags or a modification to the frame, theres a bit of a transition period around that time so its hard to tell.
If its post 1992 any old cz75B, SP-01 shadow1/2 should work assuming there isnt issues with special baseplates but I don't think there is.
If its a "Pre-B" gun you're going to have to look at used and auctions I don't think anyone is making them anymore, also a fair few retailers list magazines simply as for cz75 are actually modern -B magazines. So unless it specifically states Pre-B I would ask for clarification first.
Edit: Year of manufacture should be stamped in a oval above the ejector
