This NAA G380 has "Gutter Snipe" sights with tritium inserts. After nine years they still glow in the dark.(http://i2.photobucket.com/albums/y30/RichardS/g380-meltedpolishedguttersnipesights.jpg)
all i can say is the reason there isnt a nite sighted rohrbaugh yet is there is too thin of material in the slide to support a night sight. Though there is experimentation going on at the rohrbaugh factory to find a reliable way to have a night sight as we speak.
