7.65 ammo

Hi everybody, I asked about the 7.65 ammo a couple of days ago and the responses taught me alot.I was able to find some of the Fiocchi, unfortunatly, as so many of you warned, it didnt eject a single bullet(dang it!). So now my question is: Is it possible to find a 9mm barrel and put it on the same frame that had been a 7.65, and if so where could I find a barrel?

Also there was alot mentioned about cut down recoil springs, this sounds cheaper and practicle but what should I cut it down to? Where can I find another spring to cut on so as not to mess up the original? ( heck- that may not be the original, that might be the whole problem! I dont know.)
