I'm so glad I found this thread. During our semi-annual quals, I noticed that my 940PC's ejector rod would loosen after a few cylinders. I would just tighten it by hand when I was on the firing line. I noticed that the cylinder release also loosened up. I'm going to use the loc-tite on the cylinder release, and try the drill bit trick on the ejector rod. This is the reason I dig this forum. Thanks for the great info.
