Sturm, Ruger & Co. has always been a bit of a dichotomy of a gun company. They use the most modern of manufacturing methods, that of precision investment casting, much as would a jeweler or dental lab, to provide a near-final-sized raw part which thus requires a minimum of machining to become a completed arm. While doing so however, they have embraced neo-classic aesthetics in their arms; examples include the their Blackhawk single-action revolvers, the M77 bolt action and No. 1 fallling block sporting rifles and the Gold Label side-by-side shotguns.
The Ruger Security-Six was a solid-frame revolver that incorporated overengineered, dome-shaped recoil shields (also reminiscent of Ruger's single actions). The hammer, with its transfer-bar safety—as opposed to Colt and Smith & Wesson's rebounding hammers—was accented by its polished sides and physically more prominent than those found on the competing Colt and Smith & Wesson revolvers, suggesting this was a double action equally amenable to single-action shooting. The fact was, with its 3- to 4-pound single-action trigger pull, the Security-Six was much more practical to shoot by manually cocking than in double-action mode, given its lengthy pull requiring almost four times more pressure. Shooting the Security-Six double action was tantamount to using a grip exerciser.
In this author’s humble opinion it is the best revolver ever offered by Ruger. As compared to a Smith and Wesson I’d say there is a tiny bit of travel in single action with nearly zero pressure behind it and while the single action may not be as crisp as a S&W; I like how smooth the double action trigger is compared to the Smith. I even think the Security, Speed, and Service six revolvers’ DA triggers are better than other Ruger models, such as the GP100 and SP101. Also, Ruger revolvers tend to be low maintenance and are very easy for a novice to completely disassembly.
