With Trijicon sights, you can get a sight picture in total darkness. With fiber optics, you need a light source.
I have night sights on my carry and HD pistols (and my AR). On three of my pistols I have factory installed 3 dot Trijicon sights, and on one (+ AR) I tried XS 24/7 night sights. The difference is the 24/7's are modeled after iron sights on big / dangerous game rifles, for quicker front sight acquisition, such as would be needed for sudden self defense. Not to be confused with "normal" 3 dot systems, the 24/7 sights make lousy target sights, but excellent for self defense. The jury is still out on which ones I prefer.
On one of my pistols (a 1911) I installed fiber optic sights from Williams Sights
. They are excellent for day to low light applications, but useless in total darkness. With mine, the first time out the front fiber insert went flying into orbit. I'm trying to get it replaced by Williams
, but they say they have been having trouble with those lately. ?????
