I was surprised by my wife at Christmas with a new P99 in 9mm.  At the local gun store they did not have an extra mag, and said the s&w 99 mags were not the same as Walther.
I was under the impression they were interchangeable, but could be wrong?  Thanks.  (great site, by the way)

I believe I've seen in magazine reviews of the P99 that its magazines and those for the SW99 ARE interchangeable.  Try looking at this FAQ page for the Walther P99.  If the answer isn't there, I'm sure you can send an e-mail to the website's author:

Yes, they are interchangeable.

The Walter P99 and the Smith and Wesson 99 are identical in function and interchange without any problems.
