Congratulations on your new Luger.

You'll probably find a copy of our forum's FAQ document helpful. Just download it free by following the FAQ link at the top of the page.

The fact that you can't lift the toggle is likely related to the lock not operating.

The receiver has to be pulled back about a quarter inch before you can rotate the slide lock.

This jam up sometimes happens when the linkage between the recoil spring lever (inside the grips) and the toggle is not engaged properly.

Use extreme care when removing the grips. The left one, in particular, is easy to chip near the safety lever. The grip screws are also unique, with an unusual Whitworth British 55 degree thread.

Don't lift them far off the frame before sliding them down.

Before handling or working on this, ensure that there isn't a round in the chamber. The "loaded" indicator on the breech block will help, but consider probing it carefully to see if there is anything in there.
