Compact, lightweight and simple to use, TruGlo’s Tru-Tec red-dot sight utilizes an unmagnified 20 mm objective lens. The 2-m.o.a. reticle can be adjusted for brightness using the sight’s top-mounted, push-button controls, and windage and elevation corrections are made via two turrets. An automatic-on feature activates the optic when the firearm is moved or tapped, and the Tru-Tec automatically turns itself off after a programmable period of inactivity (between two and eight hours). The side-mounted battery housing allows the optic’s CR2032 battery to be replaced without requiring the removal of the sight from the gun. The TruGlo Tru-Tec 20 mm ships with both low and high mounting bases. Price: $220. Contact: TruGlo, Inc.; (972) 774-0300; truglo.com.

Though largely forgotten and scarce today, the Colt 1871-72 "Open Top" revolvers represented an evolution in design for Colt, and ultimately paved the way for the Colt to transition from the cap-and-ball era to the cartridge era of the Single Action Army.
