Power of P-08 ammo in the 1920's

[HisSoldier]

In another forum a guy with a very nice 1920's commercial P-08 was warned not to shoot it because metallurgy wasn't what it is now. The point was also made that one might happen upon higher strength ammo.

I maintain that the materials used by DWM, and the heat treating processes, were probably state of the science of the day, and that the strength of the action unless degraded by corrosion, fire, or battering should be almost identical to the day it came out of DWM.

It's the guns that are made today that I have my doubts about, there are some really poor materials in many guns made today because people can't seem to tell the difference between Zamak and medium carbon steel.

Does anyone know what the 9MM and 7.65MM standard ammunition power was compared to what we buy over the counter today? I would guess it's not as powerful, because of liability fears, except for +P stuff.
