The AmeriGlo yellow tritium 2-dot rear sight for Glock uses two yellow tritium lamps with white outlines in a square notch (AmeriGlo part no. GL-8431R). It is a rear sight only, so it pairs with the front sight already on your pistol. The overall rear height is 0.256-inch and the notch is 0.165-inch wide. Tritium keeps the two dots glowing in low light, which makes it a night-capable upgrade for a carry or home defense pistol.
