    Color me puzzled. Stripped my shield plus to polish some stuff up and get the slide milled and have this leftover. I can't figure out where it goes and I've looked at the parts diagram and don't see it anywhere. Dry firing it and everything works fine. No live rounds yet.

    Any thoughts?

    Just ran 2 mags worth of dummy rounds and functioned fine.

    I'm wondering if it even came from the shield now but then I have no damn clue what it came from.

    Edit: there is no extractor guide. Just a spring at the back of the extractor bar that just sits there. Not like a glock with the plunger system. More like an AR15 extractor.
