The SAAMI pressure limit for the 9×19mm Parabellum is set at 241.32 MPa (35,001 psi) piezo pressure.
The SAAMI pressure limit for the 9×19 mm Parabellum +P is set at 265.45 MPa (38,500 psi) piezo pressure.
The 9 mm NATO can be considered as an overpressure variant of the 9×19mm Parabellum that is defined by NATO standards. The service pressure Pmax of the 9 mm NATO is rated at 252 MPa (36,500 psi) where C.I.P. rates the 9 mm Luger PTmax somewhat lower at 235 MPa (34,100 psi).
According to the official C.I.P. (Commission Internationale Permanente Pour L'Epreuve Des Armes A Feu Portatives) guidelines the 9×19mm Parabellum case can handle up to 235 MPa (34,100 psi) piezo pressure.

Forum members have been advised by Jason (SCCY's armorer) on this forum that limited use of +P is fine in newer models.
Here is a point to ponder: Since Jason has explicitly stated his comments do not reflect the opinion of SCCY, and the only existing documentation states no +P, and your CPX has a problem, and you have used +P, what do you do if SCCY refuses to honor your warranty?
I am sure Jason is honorable, but you know people change jobs all the the time.
parkerd wrote:hey Jeff781 - I agree with you. Just making a point hopefully SCCY would pick up on. I was a little confused when I bought my CPX2 and saw a different picture throughout the manual. Then I found out that the manual was already quite old. Now two years later, same old manual. Maybe you think it is a little thing, but I know far too many people who might be fussed by this.
