Imight havethat sameproblem with my normal Cobra Sidewinder. Whether is was just weather change affecting my bow strings or actually the sight itself, I have yet to figure out.

I am currently trying the Sure Loc Sidewinder Model. . .I will let ya know how this one compares to the regular Sidewinder.

As far as what you can do? Sounds like Loc-Tite is out of the question. Are you tightening the sight down with the thumb tabs or the actual allen screws?

If the thumb screws, try tightening it down with allen keys instead. If you already tightening with an allen key, well, you might have stripped the threads ever so slightly and are experiencing problems from this. . .

I have heard that String wax helps keep field points locked in inserts, do you think it would work for sight pin screws?
