I detail stripped my 220 for installation of a short reset kit and found this:
This is the underside of the right rear frame rail where the slide runs. The opposite side is this way also but not as bad.
I purchased this pistol new and has always been properly lubed. I have fired less than 1000 rounds of hardball.
Surly this is not normal. I have not noticed any malfunctions of any kind.
What say the more learned of this site?
TIA,
Chris
