Power of P-08 ammo in the 1920's

[padredan]

this got me to thinking and looking at somethings. Looking to find some low power 9mm ammo that will function. or close to the pessure of the earlier military loads.I haven't reloaded in years, i have fired the two lugers i own and i am now thinking i really do not need to be. Take a look at the two pics, first was when i bought it and second after about three mags full of remington umc 115 gr, big difference there, others are calling it a luger fingerprint. one thing for i am going to be really cautious from now on, there has to be some moderen ammo out there that is safe to fire/thanks
