According to the article in this months American Rifleman, the answer should be no. Its a definite no for the .40 S&W version which is out already.
The 9 and .45, since they are not out yet, so its not impossible they'd be made to use the same mags, but I expect the 9mm to hold 19 or 20 rounds based on the capacity increase of the .40 model.
--wally.
