Tale of Two Malfunctioning Lugers, actually three Lugers.

I have a DWM/mongrel Luger and a friend has a DWM 1920 rework that is all matching, at least numbered so. My mismatched pistole, which is at least from four different 08's has developed a problem where it will not fire the second round. After maually loading the first round, firing, and then trying to touch off the second right the gun will not fire, regardsless of hard I squeeze the trigger. Comparing it to another Luger I have, a S/42, the only difference I can see is the sear bar on the earlier piece is flat at the end and the newer Luger sear bar is round. It seemed to make sense that more material there would result in a more positve firing pin release since there would be less movement of all parts to fire the gun. I added some weld material to my sear bar and and now it will not fire on the first, manually loaded round. I'm thinking I may added to much material and now there is not enough movement to allow the gun to ****. Any thoughts out there? Do I have to whittle this piece down until there is enough movement to allow it to ****? Am I looking in the right area to resolve the original problem? I have tried swapping parts but the fit isn't very good between the two pieces and I don't want to modify anything just to test this out. (The third Luger problem is the same, fires on the first manually loaded but not on the seconed semi automatically loaded round.)
My friends Luger has poor extraction and also a very light trigger that sometimes doubles. I'm thinking the sear engagement at the fring pin is so delicate that the recoil and the presence of a finger on the trigger touch off the second round. Close inspection of the sear bar and the firing pin seems to indicate that there is only very slight engagement at one corner of the fp. I am going to polish his chamber a bit to see if that helps with the extraction and also check the strength of the extractor spring. ( I did read the the thread about the mafunctioning Luger which has a similar extraction issues). Any help or advice on these issues?
Thanks in advance,
