There's more then one type of fiber optic sight. Some are better shielded then others. The TFO that comes factory on some Sigs is both heavily shielded and has a tritium vial underneath to light it up if there's no ambient light.
The down side is the more shielding the more shadow on the tube, so it won't be as bright. Even if the fiber optic rod breaks or comes out, you still have a front sight. You're just back to a black one. A few years ago I had a thread here where my fiber optic came loose at the range (somewhere after the 40k total round count on a .40 P226) and I was able to finish the range session just fine.
Others have little to no shielding and are brighter, but more at risk to damage like:
But again if the tube comes out, you're just back to a basic black front sight. NBD.
I like fiber optics and find them easy to shoot well under a variety of lighting conditions.
Thanks I am wanting to get one of the Range officer Elites, the sight was the only drawback.
