It's known as "9mm IMI" or "9mm Italian", and loaded to the standard 9mm Luger level, but develops less power because of the larger case volume, making it acceptable as a non-military caliber there.

Nope. Exact same power. Even though the case is longer they have the same OAL, case volume is the same. One of the developers of the cartridge happens to be living in Portugal now and is a friend of mine. The problem was not the power but the fact it was a military round.
