Ruger essentially built a heavy duty large frame revolver in a medium size that weighed 33.6 ounces in the 4” model. These revolvers were medium sized and were designed to be a competitor to the Smith Model 19 and the Colt Trooper. They all had a 6 round cylinder and adjustable sights.
Barrel lengths ran 2,75”, 3”, 4” and 6” Ruger made these in 38 S&W, 38 Special, 357 Magnum and 9mm Luger. The Security 6 came in a variety of calibers, barrel lengths and two different finishes, blue and stainless. They were designed to be issued to law enforcement, military and personal defense.
These are all double action revolvers, introduced in 1972 and ran until 1988. Now it is history time for this line of Ruger revolvers.
