Now I don't need to do this now, but I will someday. Someday I will want to remove the pin and extractor for cleaning in there. So I wanted to explore what I'll have to do differently with that little spring loaded button added.
For the older style, you depress the exposed button of the firing pin and slide off the little plate dealy (firing pin stop, apparently). Wear eye protection. The pin JUMPS out of there. And the extractor just slides right out.
Ok, the difference with the series 80 plunger, is that you must engage the button of the plunger before trying to push in the firing pin in to the remove the firing pin stop. Then, going by that link:
"Cover the Firing Pin opening with your thumb, and press the Firing Pin Lock Plunger again, to release the Firing Pin. This action will allow the Firing Pin to move back against the pressure of the Firing Pin Spring. Remove the Firing Pin together with its Spring. Pushing the Firing Pin Lock Plunger inwards, pull the extractor slightly backwards. You must pull it enough, so that the Firing Pin Lock Plunger can be freely removed from the bottom of the slide. "
Easy enough. Apparently, the Plunger is keyed a bit to the extractor. Good. It sounds like the series 80 system is well thought out to maybe keep things from sproinging all over the place.
Seems almost intuitive, and not nearly as hard as I thought.
One day I'll be brave enough to take one of these down so that the disconnector and sear are in one hand and the frame is in another. Of course, to be fully successful, I have to get them back IN the frame properly, too.
