Hi
As there most likely have been an amaetur gunsmith in your gun just as John is telling you this amateur might have filed on a number of places that you dont know.
You gotta send that gun to someone that really understands the Luger and have acess to the drawings of the triggerparts.
There is no reason to play around with different searsprings and burrs and **** when you not know what you are doing.
This job is as impossible for you as for a good gunsmith without the drawings, casue the drawings is the only way of determine if the parts have been destroyed.
And either is the engagement of the firingpin and the sear correct according to the drawing or do they have to be welded up or replaced.
Here is no choise in betwen and until that is done your luger is totally unsafe.
Best Regards HÃ?Â¥kan
