I have posted that I really believe the heavy spring was the cause... either alone or in combination with gunscrubber/ brake cleaner???

Now that I see someone else has this problem, I am pretty upset. I really love my Sigma and thought it was just a fluke.

I would really like to hear from people with high round counts to see just how long these guns last.

It's not so much a high round count or the "spring weight" specifically. As posted several times here it's the minimum length of the spring assembly when compressed.

Do you have any specific recollection as to what area of the frame failed?

Do you by any chance have that ISMI spring to be measured?
