Been kind of thinking about going with SS, or Tungsten Guide Rod for my Gen 4 G23. The issue I ran into when looking at the Glock Store is I didnt want any shiny parts on my gun. Their rod has the chrome looking finish. So I called to see if they offered something else. The answer I got is they are currently working on it and to keep checking the site. He said it should be long. Im happy about that.
