The initial loss of length is called taking a set, and all coil springs do this to some extent. On the other hand, a spring that always operates in the middle of its work range will last for thousands of cycles, maybe even tens of thousands of cycles... But, Luger coil springs do not enjoy that luxury! Especially the main spring and extractor spring.... The Luger springs were engineered to fit a specific space to address a certain work load that was/is close to max performance demands with every cycle... It would be an interesting experiment to put in a new spring, and measure it at 0 rounds, 10 rounds, 100 rounds, and 1000rounds... any significant change in length after 1000 rounds would probably dictate a change is needed... I know that the tape test is good for calibrating loads, but it doesn't really tell you witch is the culprit/ I find that a Luger with a weak or failing mainspring will not close consistently on the following round?.. New mainspring, and pow! Right back to normal function... best to all, til....lat'r.....GT ....

GT,
About ten years ago, we were going to work on a main spring project together. Any update here?

When I had the magazine springs made, I had an in with the general manager who was not afraid to exceed his grasp on my project! In the interim, the spring company was bought out be a large corp. and all were let go, and so went the main spring project... repeated contact efforts was met with the standard corporate, "we don't know what your talking about!" ....

.... I wouldn't mind revisiting the project, but I've so much on my plate already, that it seems unlikely in the immediate future... But, I'm still learning!

You'd think I'd be past that....

... So, anything is still possible! best to you Bob, til....lat'r.....GT....

This is an interesting topic, because I was still in doubt whether I would change the main spring in my BYF 41. It does feel much less strong when I work the action then the one in the p08 of a friend of mine. I also found some damage on the back of the frame.

But my question now is. Is Wolff the best option out there?
