I just bought a m10, 4" pretty grungy. When taking apart to clean up one grip panel didn't want to come off. I took wooden
dowel and gave it a tap from back. It popped right out but the
grip washer was rusted to frame and medallion rivet popped
through washer leaving it in frame. I squirted in with Kroil and
got it loose. I now have the medallion end with mushroom end
that won't pass through hole in washer. I am thinking of using
Dremil to remove "mushroom" on rivet shaft and attempting to
restake it. What do you normally back up the medallion with
when staking? Should I center drill rivet to help it expand? Never
done this before, advice from someone who has appreciated.
