Completely off the top of my head:
If you HAD to have it in 9mm couldn't you take the top end off a Taurus and mount on the frame or does Beretta have a larger frame on the .40's than it does on the 9mm?
Granted, not the most practical thing but the Beretta does sound a lot like the Taurus 92. Kinda like a knock off of a knock off.
