Used Ruger Security Six 357 Mag Stainless Steel 6" Barrel Circa 1981

The Ruger Security-Six and its variants, the Service-Six and Speed-Six are a product line of double-action revolvers introduced in 1972 and manufactured until 1988 by Sturm, Ruger & Company. These revolvers were marketed to law enforcement duty issue, military, and civilian self-defense markets. 

Introduced in 1972, the Security-Six was the original model of the new series. The majority of these guns were manufactured with adjustable sights, though a few early models were sold with fixed sights. Security-Sixes could be ordered with either service or "target" (combat) -style square butt grips. Nearly all Security-Sixes were chambered for the .357 Magnum cartridge, which also permitted the use of the shorter .38 Special cartridge. Ruger also chambered the Security-Six in .38 Special for some police orders by fitting different cylinders that could only accommodate the .38 Special cartridge. Barrel lengths available on the Security-Six included 2.75, 4, and 6 inches.
