You know, Ruger has a pretty good rep for fixing things that aren't right. I'd give em a call, as spend a couple of bucks to send it to them.
My one and only problem with a Ruger was a well used Mark I Target that suddenly decided to go full auto one day. Packed it up, sent it to them, they fixed it and sent it back for free. That's why I bought more Rugers. I kinda like dealing with a company that stands behind their product.
