You know about the cylinder pin safety, right? One position keeps the hammer from hitting the firing pin, a much better design than Ruger's transfer bar which I have had lock the gun up by hanging under the firing pin.
Better exactly how? The only way a Ruger will do what you describe is if the cylinder pin is not all the way in, and locked in place.
The "Swiss Safety" isn't exactly user friendly if you needed to get it deactivated in a hurry.
The Virginain Dragoon should be handled like a traditional Colt style single action , or 3 screw (non transfer bar) Ruger, and have the hammer down on an empty chamber.
They are NOT to be carried with 6 like a New Model Ruger safely can be.
