Saami have lowerd the maximum allowed preassure limits.
That is very noticiable in some European cartridges cause they have lowerd it as well in order to be able to export it to the US.
I have competetivly used a lot of low powerd Speer Lawman ammo in my bull barrel luger and with exelent results.
But on the other hand I have a pretty weak mainspring.
However the american ammo manufactured today is much less than the Service ammo made originally for the luger.
