I found your problem. ^ ^ ^
On a more serious note, there are some posts on this blog
(they should be lined up for you if you follow the link) about what looks like the same problem. This apparently showed up from time to time on this model. From what I understand, newer editions shouldn't have this problem, but I'll leave that to you to sort out.
I bought a P238 that was used but unfired, and I think it's one of the newer variety. I was worried about this happening, but I was lucky, I guess...no issues (knocking on wood).
The good news is that it appears Sig will fix the problem and get you up and running.
