I was gonna suggest Mec-Gar magazines. It seems you have one of the very few pistols on the planet for which you cannot buy Mec-Gar mags. Well... actually you CAN buy Mec-Gar mags for it. They just say "Walther" on them and cost $50-ish a pop. 
The good news is it looks like you can use S&W 99 mags. Good luck finding 10 rounders...

The magazines are Mec-Gars, with anti-friction coatings. Walther apparently doesn't allow Mec-Gar to sell them under their own name, so they're expensive, but the P99 has also been made under license as the S&W 99 and the Baby Desert Eagle, and those also source Mec-Gar magazines. So reasonably-priced magazines are not hard to find, and they're all top quality.
