Toggle sticking open

No, but there are a number of people who are thinking that despite the age, the main spring may be weak and need replacement.

One thing, as I think about this, is that I haven't considered that the mainspring that was supposedly replaced could have been replaced with a weaker one than original. That could be why it looks new but is potentially failing. It is one explanation that would fit the circumstances. The exact same thing happened several years ago on my P226 when I replaced it with a spring that was 30% lighter than the original. It lasted a couple of years and one day, all of a sudden, stopped striking primers hard enough to ignite. So I'm going to wait and see when I get new springs.

There still feels like some sort of interference in the pulling of the toggle, so that has to be considered.
