No, applying the safety should only prevent the sear engagement from being lost... and thus "safe"
It does not normally press the sear 'back' into the correct position.
Having the gun checked by Hugh or any another Lugersmith is a good idea if you are not comfortable with the current safety posture of your Luger. Can you duplicate the accidental firing with a empty but primed case as the feed object?
(only attempt this outdoors and with the gun pointed in a safe direction because a primer report indoors is much louder than you think)
If you can duplicate the occurance, I would say that your sear engagement is insufficient and the gun should be repaired by a gunsmith.
Thats my
