High-tech circa 1970...
Get ANY Ruger DA, from the Security-Six to the SP-101, and you've got cutting-edge revolver technology that WORKS. Nothing more modern than stainless in materials, but you also have none of the locked-up cylinders or glitchy actions that seem to afflict the current on or off-shore raging revolver merchants. Buy an old Ruger and be happy, because it still don't get much better than that.
