The blueprints show a 1,2mm rounded tip and cylindrical protrusion on the front tip of the firing pin. The actual amount probably is slightly less, perhaps 1mm to 1,1mm.

The area milled away for the case head to fit into the breech face is 1.5mm deep.

If you dry fire a Luger with nothing to protect the firing pin, it could possibly peen the inner surface of the breech block and push farther through the face of the breech block.

If the linkage and axles of the toggle train are worn, you could end up with headspace issues. Are you getting pierced primers?
