I recently bought a very tight mk I.. mfg date 1977. It is in exceptional condition overall and shoots well. while cleaning it last night i noticed that the ejector has some movement.. about 1/16 laterally and almost none vertically. i dont remember any discussion about this problem on the forum... anyone else ever have this problem? I have no idea how to fix this, as it is riveted to a frame member.. i guess it will be headed back to ruger.
