James, one other thing to pay attention to is how you are supporting the Luger while you shoot it.

You need a very firm grip straight on that transmits the recoil pulse down your arm and into your shoulders. One or two hands will work. It's essential that the grip not rotate vertically in or with your hands.

Don't use high energy rounds. These pistols were not designed for higher pressures.

After following Doug's advice, consider the following:

Depending on it's condition, you could also be dealing with a recoil spring that is out of spec. The timing of a Luger is very balanced.

First, try the more standard power loads like the WWB 115gn we recommended in your other posting. Then have a look at how smoothly the magazine is functioning. Do not try and disassemble the magazine. If you suspect a problem there, get in touch with Gerald (G.T. on this forum) and chat with him about it.

After market magazines vary in quality. Most here recommend the MegGar, but I don't have any to evaluate.

Check the hold open and it's very small spring to make sure it's seated correctly, and that the channel it rides in isn't dirty or corroded.

Check the extractor and the channel it rides in to make sure it's seated correctly, and that it's well isn't dirty.
