One of my 500s has been misfiring about every dozen cycles.
Takedown and cleaning did not fix the problem then I discovered from watching the firing pin after snapping the hammer, that the firing pin does not come out of the flash hole. Finger pressure or a tap on the hammer will bring it on out. I suspect there is a burr or debris inside the firing pin housing and want to remove it to clean.
So, how is the firing pin removed? I see a side pin to that housing but my attempts so far have not figured it out.
What's the combo?
Thanks!!
