When purchasing Trijicon or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

Sights with glowing dots are proven to be more visible and accurate than standard black sights in low light shooting tests. They have rugged, self-luminous, 3-dot Tritium lamps which provide their own long-lasting energy source. The lamps are mounted in silicone-sealed, metal cylinders to give maximum protection from breakage or leakage, and polished sapphire crystal windows give a bright, crisp and perfectly round aiming dot in low light. White rings are inlaid around each sapphire, which make the sights appear as standard white dots in daylight. The very narrow blades do not have the white ring and will look more like a plain black blade in daylight. Most of these sights can be installed in factory dovetail or sight base. However, Glock models require the use of special Trijicon installation tools to avoid sight damage.
