The transfer-bar prevents the hammer striking a cartridge without the trigger being pulled, hence preventing accidental firing.Īvaliable barrel lengths are 4.625in (117mm), 5.5in (140mm), 6.5in (165mm), 7.5in (190mm) and 9.5in (241mm). In 1973 the 'New Model' Single Six was released, featuring a transfer bar mechanism. Being a single action, prior to 1973 atleast, the Single Six couldn't be safely used with all six chambers loaded for fear of accidental discharge. The Ruger Single Six was designed as a single action revolver, a novelty in the 1950's with the main single action revolver, the Colt Single Action Army, going out of production before the Second World War.
