The mags are almost exactly the same. The only difference is the width of the feedlips. With the 40 being slightly wider for the larger shell, and the difference in markings on the witness windows.
9mm will feed reliably from the factory 40 mags.
Other than the barrel, there is no need for further mods. They even use the same recoil spring.
Also the same if you want to get and can find, a 357 sig barrel, I might add.
