Not avoiding anything, I just didn't check the messages

. Sorry.
I think that the vast majority of the pistols have no problems, and we will never read much about them on a forum. We will hear about the problem ones. The common failure that we hear about is extraction. Now come to think about it, the problem seems to only be in 9mm. The .40s have feed problems but not extraction (unless my epiphany is wrong

). So the common failure can be FTE and still be uncommon per capita.
When pistols go into SA for fixing, they comment that they either replace or tune the extractor and this fixes it almost every time. So I believe that the single extractor part is the problem (for brass left in the chamber). Short strokes would cause the stovepiping, but you should be able to check this by intentionally gripping hard, or having a few others shoot your pistol and see if the problem follows.
Revolver people sometimes have problems with the semi-auto since they often let the recoil happen in the wrist. If your experience is mostly revolvers then see if the solid wrist helps. Your FTE description sounds like it is halfway between so I don't know for sure.
There is another thread where the member shows a picture of the extractor on the brass, and I explained another of my theories there.
