The timing of the action in a Luger is more precise than in modern firearms.

Even the angle of the forward facing edge of the frame ears had to be adjusted over the early life of the design. There have also been a relatively large number of different recoil springs specified for different model and era Lugers.

The action depends upon good support during cycling and the correct mass and energy power curve combination in order to cycle just right. Too much and it will mis-feed or stovepipe. Too little and it may not cycle completely. Powder is available in a complete range of burning speeds and power curves, but the question is "what is used in a manufacturer's ammo"? Someone like Winchester probably uses their W-231 (Hodgdon HP-38) powder in their Standard Velocity 115gn ball ammo. Most don't disclose what they actually use, and probably shift to different powders from time to time.

This pistol was, for the most part, designed through experimentation without the measurement sophistication available today with modern high speed photography and similar visualization tools.

Find an ammo that is not too powerful that will properly cycle it. We suggested starting points.
