where to find pre-b cz75 and cz85 magazines

[samjossha]

Hi all I have a cz85 manufactured in 1987.  I bought it a couple of years after that, nib, while I was stationed in Berlin Germany.  I've tried a number of mags and can find none that fit.  I fella at a show told me that he had one too.  He said he filed his down a bit inside to make modern mags fit, but said he would not recommend that mid for a novice. Can anyone advise on where to find mags to fit guns like mine, or speak to the possible mod.
Thanks,
Sammy
