Frequently, I am asked what sight configuration I prefer on a duty pistol. Most of those in law enforcement prefer tritium sights as that has what they have been taught as being the best to use in case of a low light encounter. While I am certainly not here to say that tritium inserts are a poor choice, they are not mine. My favorite choice of insert for a front sight is a fiber optic front with a black rear. I find that in most daytime lighting conditions, the front fiber is able to gather enough light to glow as bright as an Aimpoint dot. It is extremely easy and fast to acquire, and has held up quite well for me in work and off-work applications.
Recently, Frank Proctor posted an excellent article on this very topic on the RecoilWeb website. His article outlines some of the durability concerns as well as the advantages of the use of the fiber optics on pistol sights. The short of it is that if you’re carrying a pistol, you should have a light either with you, or attached to the gun. And if the fiber breaks or falls out, the front sight is just as usable as any set of non-illuminated irons.
