Send it back to S&W. Even better send it to LSG manufacturing. he's a certified S&W warranty service, and he never asked me if I was the original owner of the gun. The warranty was honored, shipping paid both ways, and he'll give the gun a whole once over and do what needs to be done. S&W has the best warranty in the business. Parts break. Ask any 1911 owner how they have to baby their guns. The 5906 is a workhorse that will outlast your grandkids. Don't give up on it.
