The +p+ refers to pressure levels, and not necessarily velocities. However, the factories do load to higher velocities with higher pressures.

But as far as hotter, yes, a fast burning powder could be loaded so hot it would blow up the gun. You could get +P+ pressures with no greater velocities or even less than standard pressure loads.

FWIW, my Kahr P9 is not rated for +P+, and before I learned that I did have some malfunctions with +P+ ammo. The factory rep told me that those pressures caused slide velocities that resulted in malfunctions. I do not get malfunctions with +P. My G26 gets the +P+ ammo I have.

Regards,
Jerry
