Looking for reliable magazines for AT84S - 9mm

I recently acquired a 9mm AT84S semi-auto pistol made in Switzerland. It’s in excellent condition. I bought it from a friend who had shot it successfully for some years, and I look forward to many years of successful shooting as well. I want to acquire some new condition magazines made expressly for this pistol – that will work reliably. Where do I go?

CDNN had them on sale, but I don't know if they have any left in stock. Early Tanfoglio TZ-75 mags will also work. I don't think that the new 9mm Tanfoglio mags for the one size frame will fit, however.
