By Jove, the loctite 609 "may" have worked.
Put in a couple of drops an hour and a half ago. It actually wicked right down the to the area where the site and slide meet (the area between the posts).
You can see it around the edges of the sight.
After an hour or so, no wobble. But it takes 24 hours to cure, then we will see how it does shooting. This may have worked.
