Gunman and Daryl, Here is a footnote very consistent with your comments. Looking closely at the "spare" strikers in my case, I don't think they are spares at all, but rather the originals likely replaced by strikers without the mechanical extractor elements. A closeup photo shows that the two strikers have three elements: the firing pin itself, a post that exends in the opposite direction to the firing pin but parallel to it and a rounded horizontal extension that is perpendicular to the firing pin. Here is a closeup of both pins together showing that the post on the right striker is broken and shorter than the other, leading me to think that these were the replaced originals after the system broke down. In the next post I will try to get a decent photo of the striker from another angle showing the rounded horizontal element. Is this the part of the system that slid in the groove?
