A post in another thread got me thinking about this again, and you do see this question crop up frequently in one form or another.
Do SAAMI and CIP have different specifications for the maximum pressure in 9x19? SAAMI standard pressure 9mm is 35,000 psi. What about CIP? I've read elsewhere that CIP specifies approx. 38,000 psi for 9mm, which is close to what SAAMI considers +P. That's just the figure I've read on various Internet forums -- I've yet to find the definitive answer published by CIP.
So, is the SAAMI spec for 9mm truly "dumbed down", or is that just a myth?
