As I have been reading around lately, I have seen a lot of comments about fiber optics being "too bright" in certain conditions, or in general. And not only on handguns, but rifles, bows, etc. But handguns seem to be one of the major considerations for sight changes.
So if somebody is considering fiber optics, you have to know how they work. A fiber optic line is made for energy to run down the line on the inside, not exiting the sides. - In weapon sights, the sides collect light, which is channeled down the line, to the end - this is the flat round part on a sight. When purchasing a sight the longer the sight, the brighter it will be, the shorter the sight, the darker it will be. If you are considering this type of sight, look around and find one which matches the brightness you are looking for.
If you are in certain conditions which you find your site too bright, the solution is very very simple - white out or non-translucent tape (think masking tape). So since the outside of the line collects light, the more surface area to collect light means brighter site. If you cover some of that area with white out or tape - instant darkening affect. Since fiber optics are made of plastic, I dont recommend using adhesives which could be harsh, such as nail polish, paint, etc. And also, white out is easy to scrape off when you want it gone.
On my bow I have the fiber optics with ten-fifteen or so loops of line.... they were too bright, so I just broke the lines off at a certain point, problem solved.
Just thought somebody might be able to use it....
