I have a P229 in 9mm - I Had it for 3 years and around 1500 rounds through it - one of my favorites until it started failed to eject / double feed.
Tried a number of things with the same result. One or 2 rounds every mag would jam.
I had some extra time AND some 2x readers and noticed a build up of carbon / residue on the face of the extractor. (yes, I do clean it regularly) Spend considerable effort and removed the mess. Went to the range today - 6 mags through and no more issues.
