Hi Erik
Your jamming does is likely not caused by to hard ammo.
Most often is the jams caused by to weak ammo compered to the extremely hard recoil springs a lot of those guns have.
The best as I see it is to try a cuople of more magazines and have the gun checked by a gunsmith who knows lugers.
The reason for having the gun checked is not that i think it can blow up in you'r face but the fact that many of those guns are to much manipulated by people in the past.

Ps. Thanks john for your kinds words.
