I have the same problems of availability in Germany.
CZ said their subdivision in USA came up with the idea of
that certain SA version of CZ75. The demand for this particular model is very low in Europe because they are offering other guns like the IPSC or Champion version for sports shooting, therefore they are not sure when or if they will put the SA on their official webpage. But I should contact my local distributor to order one (directly from factory in Czech Republic, I believe).
Well, thats what I did and they told me in return there is no such an "SA" model on the CZ European pricelist (yet?).
Since I dont have a permit to own guns yet, I didt pursue the SA matter any further last year.
