STURM, RUGER &CO. ~ SECURITY SIX ~ .357 MAGNUM

Produced - 19721988 Although medium-framed in size, the Security-Six was somewhat stronger than competing guns like the Smith & Wesson Model 19 as the Ruger featured a thicker frame without a sideplate cutout, a stronger barrel shank support that prevented catastrophic barrel failure in the six-inch model revolvers, larger, stronger internal parts, and an increased diameter cylinder with offset bolt locking notches.
