Most European SMG 9MM ammo was loaded to the same pressure specificatiopns (CIP) as any other 9MM ammo. The difference was a very hard primer that was needed to prevent premature ignotion in fixed firing pin weapons.
I purchased a quantity of both German and Egyptian military surplus ammunition. The German ammunition was from the war.
Niether would fire in my SIG-Sauer or Glock handguns. Some would fire on the second strike. I donated that ammo to the sheriff, and I was told that it functioned with 100 percent reliability in their SMGs.
I've used several thousand rounds of recently manufactured so-called SMG ammo from IMI.
These were used in my SIG-Sauers and registered the same velocities on the chronograph as any other NATO specification ball ammmunition.
