The Story
This Meprolight Tru-Dot Rear Night Sight is a great accessory for shooters who don’t want to pack their firearms up when the sun goes down. This self-illuminating rear sight replaces the stock iron site on Glock 9mm, .357 Sig Sauer, 40 Smith & Wesson and .45 GAP pistols and uses a phosphorescent gas called tritium to illuminate the sight markers for day and night visibility. The tritium gas eliminates the need for batteries and the sights are guaranteed by Meprolight to provide usable illumination for 12 years. This rear sight is custom designed for Glock 9mm, .357 Sig Sauer, 40 Smith & Wesson and .45 GAP pistols to ensure a perfect fit and feature green illumination.
