1911 - Diagnosing mangled cases

Recently a fellow took his Dan Wesson Pointman PM2 to the range to have some fun. What he got instead was mangled brass and constant jamming. He posted a couple of pictures showing the cases.

I looked at the pics and immediately diagnosed an extractor that was losing control of the empty cases during recoil causing them to not eject. The empty cases would then sit on top of the next round in the magazine as it was being fed. The empty cases would then get slammed into the barrel hood. I've experienced this specific malfunction in the past so was confident in my diagnosis.

Eventually the fellow set about removing the extractor from the slide and discovered the firing pin stop had suffered a catastrophic failure. While my diagnosis was technically correct, it wasn't due to a bad extractor as you can see in the picture below. The broken firing pin stop allowed the extractor to clock like crazy which caused it lose control of nearly every extracted case.

I don't think I've ever seen a firing pin stop fail like this one.

The FPS is pretty worn / messed up, but I'm guessing it's a P/M or MIM part, and didn't get either compacted to proper density or sintered at the proper temperature for the proper time.

Did he get a new FPS in it, and if so, how does it run?

He bought and fit an EGW flat bottom FPS and the pistol is running fine.

You can see a lot of porosity at the break. Bad steel. I never heard of this part failing either.
