@jetfire That qualifies as battered! Not good at all, but I can now divert my attention elsewhere. Thanks for sharing this.
Yeah, what's interesting is that if this had been a MIM part, it's a lot less likely that this would have happened, you know? Since it's easier to get good quality control and heat treating on MIM, it's a lot harder to get a bad small part. I'm going to assume that's what happened here - the part wasn't heat treated correctly so it's way softer than it should have been, which is what smashed it up.
When talking with some friends after we heard the news, I (terribly) photoshopped one up on request. The length is in no way correct, probably like 2.36" barrel or something. Enjoy.
Charlize Theron took a short barrel MR73 from a French agent in Atomic Blonde. They became very, ummmm, friendly not long afterwards.
This is half right as to identifying the underlying cause, but dead wrong as to the general claim. All it takes for a revolver to resist the wear of its cylinder stop and the peening of its bolt notches, in theory, is satisfying one metallurgical and two mechanical requirements:
- The cylinder notches and the cylinder stop must be made from an appropriate alloy heat treated to the point of preventing their mutual impact from reaching the yield point of their material's stress-strain curve within the physiologically attainable speed of human trigger pull;
- The cylinder must be light enough to keep its maximum rotational momentum within the elastic performance envelope of cylinder notches and the cylinder stop;
- The cylinder stop must be light enough and sprung to the point of keeping up with the maximum rotational velocity physiologically attainable by human trigger pull.
Ensuring the compliance of manufacturing practice with the requirements of mechanical and metallurgical theory is left as an exercise for the reader.

I’ve got to wonder if competition-speed DA shooting is within the MR73’s design envelope, or is it something like a Python which was designed mainly for single-action shooting?
The MR73 was designed and manufactured for social work within the parameters dictated by GIGN, based on the contemporaneous FBI training doctrine, which encompassed both single- and double-action shooting, depending on the tactical requirements of the moment. Sixgun gaming falls outside its remit.
