Absolutely no experience with the Red Label, rattling or not. I have, however dealt with Ruger on several occasions involving my Rugers and those of friends. My experience is that, if you own a Ruger and it doesn't work, it will be made right-even if the problem is clearly the user's fault and not Ruger's. I have never been allowed to pay for the service or any of the parts I have been given over the years. While I am the original purchaser of all of my Rugers, I have helped with two which had passed through many owners before landing in my friends' lockers-they received the same service. Call them, they will advise you how to get started.
