Baby Luger Breech Block Slap

[milesc2]

Don,

I think leaving it as is may be the best answer yet. Your right about the double spring setup. I just tried to make one with a C96 mainspring and came very close but there just wasn’t enough room.
Also did GT’s measurement test and have confirmed it’s the longest possible spring that can be installed.

Your last point got me thinking... Could a small amount of material be removed from the back of the breech block? It seems as if the parts coming into contact are hitting very slightly, just enough to leave a mark. Maybe if a little material was removed they wouldn’t touch?

I am not removing it myself again... It was a miracle I got it back together without scratching anything!!!

Here are the requested photos. Please ignore the fingerprints.

Best,
-Miles

Hi Miles! Hey, you might have an interference issue in that it is impacting inside while not reaching the stop on the rear toggle outside? check it without the mainspring for travel and clearance?
On the mainspring... there are many different wire diameter variations right in the Luger mainspring family! I've seen them from .0535" all the way to .0685" and I'm not sure what the Wolf springs are at the moment! But, if you haven't an interference issue, then you need to measure the main spring wire size and go up a few thousands, with all else being relatively equal, you should be able to cure the issue?... ... I have some used take out springs that you can have to play with, just need to know wire dia. so we have a benchmark to start with?.... best to all, and Hi Don & Rick .... With these two guys on the hunt, and picking up the scent, the best dogs are definitely running!! best to all, til....lat'r....GT
