I have 5 pistols with them, at last count. It is a logical upgrade, even though the gas stops glowing after a few years.
The house AR also has Troy BUIS with tritium inserts. Probably overkill, considering the other sights on the rifle, a Leupold Prismatic and a laser grip, but backups are backups...
The sights that have the white outline around them are my favorites as they are visible in all light levels.
Except for pure target or hunting guns, I am inclined to have night sights on just about all defensive weapons. A couple of my best 1911's will get them, at some point.
