One notable exception is the 9mm Italian Glisenti cartridge. It is a 9x19, but loaded weak specificly for the Glisenti pistol, and while identical in dimension to the 9mm para. is essentially considered a different cartridge...
Yes! The high pressure versions of the 9x19mm cartridge might shorten the service life of your now century old Luger, but they won't blow it up.
Keep modern cartridges out of your Italian Glisenti, and to be on the safe side, keep those +p and +p+ loadings out of the older guns.
It is not a bad cartridge. When you hear me refer to it as "Kaiser Wilhelm's" cartridge, I am just making fun.
