Sorry Steve
But your advice is pointless.
Just as Ted is pointing out the action is moving extremely fast and if some "amateurgunsmithexpert" sometimes in the past have adjusted the triggerpull by altering the engagement betwen the sear and the firing pin then they will never see the problem while cykling it by hand.
They will maybe not see the problem when shooting a box of ammo either.
But sometimes now and then the gun will maybe emty a mag on less than 1/2 second.
I have said it before and I say it again.
A reliable Luger MUST have the sear and the firingpin engagement parts blueprinted to be reliable and safe.
If you don't have the drawings and the measurement tools please handle over the gun to someone who have it.
