Hey guys, new to this forum and to a Kahr PM9. Just put my 500th flawless round through her tonight and did a thorough cleaning, only to realize afterward that the white dot on my front site is...gone. I don't know if it was an application or just paint? Anyone else have this problem? Suggestions for what to do about it? First thought is to just fill in with paint but I can't even put a bumper sticker on straight, and is there a certain type that will hold up better? Ideas anyone?
