Compared to what exactly? 9 is an inferior subgun round? Hmmmm.IOW, an inferior caliber.

Oh no. ^^ Another caliber war!!!!
While the SAAMI system (psi) reads directly in the chamber, NATO and Europe (CIP) measure the pressure ¼ inch in front of the case mouth. This means the bullet will have to move past the transducer port before a reading is obtained. Since the NATO and European system sees a larger volume for the gas due to the bullet movement, ammunition loaded to NATO or European specs will test as over SAAMI pressures in a SAAMI test barrel.
To Jungle; Thank-you for a very clear answer......It is largely a myth that NATO spec 9mm is hot loaded. Do a search on chrono results and you will see that most of it falls well within the range of standard pressure loadings in terms of velocity. The NATO spec method of measuring pressure does differ slightly in that they refer to peak pressure and we refer to average pressure in the US.
In the past there have been some lots of very hot subgun ammo made and they aren't recommended for pistols.
Any modern 9mm should handle any recent NATO standard loading without a problem.
Commercial european ammo imported into the US is made to comply with US standards and the european standards. It is almost the same standard, but stated differently.
Kace, The marking on your CZ is a NATO stock number, meaning that type of pistol has been approved for NATO purchase. It differs not one whit from a standard CZ without the marking in it's pressure handling ability.
What type of ammunition should I use in my Ruger 9mm pistol?
The Ruger 9mm pistols are chambered for the 9x19mm NATO Parabellum (9mm Luger) cartridge, compatible with the U.S. and foreign military or commercial 9x19mm loads manufactured in accordance with NATO, U.S., SAAMI, or CIP standards, including high-velocity, subsonic, tracer, hollow point, ammunition loaded in aluminum, steel, or brass cartridge cases, +P and +P+ ammunition.'s
