Which 9mm is built specifically for 9mm NATO/European standard pressures?

To my knowledge, all western European built pistols produced by members of the CIP are proofed with 30% overpressured rounds and will bear either markings on the frame or the barrel to indicate passage of firing the proof loads. I would have no second thoughts about putting "hot" 9mm ammo through my Beretta PX-4 as long as I know my current recoil spring is up to the task.

Before the Brits REGISTERED pistols were confiscated, there was quite a lot of surplus 9mm military ammo on the market, at least some of this was reckoned to be for SMGs. Almost all of it was corrosive primed.

Pistols which were not good at digesting it were:

Walther P38s; cracked slide rails and battered frame rails.

Berrettas; separated slides

Lahti L35 Bolt blown out of the back (Peter Kekkenon put the problem with SMG ammo down to longer duration of pressure rather than peak pressure, the L35 design assumed no pressure in the case following bolt unlocking)

Luger (Full auto burst then bent toggle, I didn't see it and I suspect that the gun had been messed with, I heard a rumor that its' owner was arrested some months or years later and sent to secure loony bin for firearms offences).

Browning GP35 was reckoned (anecdotally) to be the only gun designed to handle it regularly, though with suitable slide and sufficeint travel before unlocking coupled to decent buffer to stop the slide, I don't see why most closed slide autos shouldn't be able to handle it.

The story i heard about reduced loading of US 9mm was to prevent Glisenti owners blowing their faces off, as the rounds share the same dimensions but the glisenti pistol was designed around a lighter loading.
 
I have 50 rounds of 1986 TZZ 9X19mm ammo. The bullets (FMJ) have a black tip. Does anyone know what these are. I was told that these were for sub guns. I was in Ft. Bragg when I got them.
 
CIP standards are slightly different than SAAMI standards due to the methods used to measure them.

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.

Attempting to compare them without due regards for the differences in parameters will lead to incorrect assumptions.:)
 
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.
To Jungle; Thank-you for a very clear answer......
"Any modern 9mm should handle any recent NATO standard loading without a problem."
 
All Ruger 9mm pistols.


This is from Ruger's website under the FAQs section....


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

Go Ruger!!!
