Like the others have recommended contact Ruger's Customer Service. I have first hand experience with their customer service and they do a fantastic job. My only complaint is the first time I sent it to be reassembled when it returned the saftey was not working right, so I had to send it back. However, they appologized for it not working right, so they sent me two free magazines as compensation for having to send it back.
