That was kinda my thoughts sub gun. I asked about the specs on it and this is what i got back in reply.
The 9mm 115gr Police ammo is loaded to the European C.I.P. specs Instead of the US SAAMI specs. What does that mean?
SAAMI measures pressure in the chamber, while C.I.P. measures the pressure ¼ inch from the case mouth. C.I.P. recognizes a larger volume for the gas due to the measurement placement. Ammunition loaded to C.I.P. specs will test over SAAMI pressures if tested in a SAAMI test barrel.
The ammunition will be hotter than a normal 9mm 115gr loaded in the US. That is why we gave it the +P designation
