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
