Try looking at this Walther FAQ webpage for some explaination. It seems if you contact Walther (or S&W) and get the newer blue-topped mags, you will be in good shape.
Nice to see more law enforcement is using this weapon. It is an excellent pistol. I own a .40 and greatly prefer it to any 9mm I have shot. I recently qualified for my concealed-carry permit with a 95.8 on a 50-round course with my P99.
