ALSO - while I had everything out of the frame, I noticed a little "lip"
or "flash" on the bottom of the hammer pivot pin hole (inside the frame).
With just the pin installed, it projected out past the back of the slot,
preventing the tab on the ejector from seating fully. The Ruger tech
said it's not supposed to be there & to file it off flush with the little
ramp on the inside of the frame that the tab fits aganst.
Sorry, I didn't get a foto of it before I took it off.
