That's actually a good idea that would "kill 2 birds with one stone". The .40 S&W cartridge runs several dollars a box more, even for cheap FMJ practice ammo. By purchasing a second 9 MM barrel one could shoot FMJ 9 MM for practice for about the same cost as it would be to go through the hassle of reloading .40 S&W.
I never got involved with the .40 S&W because I've always considered it somewhat of a "backward development". By that I mean when S&W came out with the .357 Magnum cartridge back in 1935 they basically took a .38 Special case and lengthened it to produce what was then the most powerful handgun cartridge in the world. Fast forward to the .40 S&W round which is nothing more than a shortened, down loaded 10 MM. It seems police and law enforcement in general had the same trouble with the 10 MM as they had back in the mid 60's when S&W came out with the .41 Magnum round. That round was designed as a compromise between the .357 Magnum which was a bit too little, and the .44 Magnum which was way too much for law enforcement. Especially in urban areas. So I guess S&W felt it was time to reduce power for cops, rather than increase it. That idea appears to have worked. The .40 S&W is a smashing success. The Department of Homeland Security just ordered 450 MILLION rounds
