The TruGlo Tritium Pro 3-Dot Night Sights (brand part number TG231Z1W) bring a classic three-dot sight picture to low-light carry, pairing a white-outlined green tritium front dot with a two-dot green tritium rear so your eye reads the same triangle day or night. TruGlo assembles the set in the USA with Swiss tritium for a bright, reliable glow, and the front lamp’s FOCUSLOCK ring keeps your point of focus consistent from draw to draw. The 3-dot layout is one of the most widely trained sight pictures on the market, making this a straightforward upgrade for defensive or duty pistols that fit most standard holsters.
