When purchasing Meprolight 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.

If other sights fail, the TRU-DOT sight is the go-to, with its self-sustaining green tritium gas light sources in both front and rear blades, offering a three-dot green/green sight picture (with some models available in green/yellow or green/orange). The front sight is always green for optimal contrast with the rear. It's weather-resistant and immune to gun solvents and oils; trusted by the U.S., NATO, and Israeli armies, and highly recommended for law enforcement and other precision work in low-light settings. Plus, it's easy to install: either replacing the rear sight entirely or fitting over the original blade (in most guns), and the front sight replaces the original (for 1911 Autos), slips over and pins onto it (for some autos), or replaces the colored insert in S&W Autos. And with a 12-year factory warranty, it's a sound investment for any shooter.
