Until the fiber optic breaks!I've had truglo tfo's on a few. They are pretty nice. They glow bright at night, and they really "pop" in the sunlight as well.
Trijicon HDs hands down!
I have big dots on my 19 and like it well enough
Trijicon HD rears are barely visible in daylight, and subdued at night, almost as perfect as no rear dots! The front, in Orange, or Yellow is extremely easy and fast to pick up in daylight, and glows just enough to be fast at night!I haven't tried the Trijicon HD yet. I don't know if I would like them or not. I like a thin front blade and a normal or smaller dot. I use the Warren Tactical 3 dot on my 19. They have a thinner front blade, a slightly wider rear notch and the outside edges of the rear sight are cut away. The rear dots are yellow and a little dimmer than the front green dot. They have a very clear sight picture.
I am a fan of Trijicon HD night sights. Yellow front post.
