Standard Dot front sights use a patent pending glow dot that absorbs light and glows in low light levels before it is dark enough to see the tritium. Green is a great option for low light and has a very bright glow intensity. The surface area of the convex dot increases light absorption, intensifying the charge of the glow properties of the dot.
