My new Ruger Wranger is a winner, no doubt. I don't know much about the "zinc alloy" that is used for the grip frame. The cylinder frame is aluminum. Is this just a coast cutting move? The only reference I have to zinc framed guns are the cheap .25 autos that guys would carry around in my neighborhood when I was a kid. They would be considered junk by todays standards. How well will the zinc frame stand up to a drop on the sidewalk?
