I realize the Fire Selector or as we would call the Safety has an audible, loud "click" as it is put on / off safe. However, after shooting my FS2000 for a total of 360 rounds, and numerous times putting the safety on and off for familiarity, my fire selector has developed a loud "squeak". This squeak is much louder than the normal "click". Is this normal? How can I suppress the noise? Silicone or dry graphite?

I accidentally spilled some CLP on mine while I was cleaning it, and the selector/safety is smooth and no longer sqeaky now.

I am sure anything compatible with that plastic is just fine.
