In order to answer your question I would need additional information. Specifically, what is the crime that you were charged with in 2003?
Washington statute does allow for restoration of gun rights, but certain criteria must be met. The conviction of certain crimes like murder, robbery, kidnapping, assault, some drug related crimes will prevent you from petitioning the court for your gun rights back.
If you have been convicted of a crime which does allow you to petition the court, you must meet additional time requirements. Again, depending on the nature of the crime convicted, you will have to have a certain number of consecutive years without convictions.
This process can be very frustrating and confusing. I suggest that you speak with an experienced attorney who can review your specific circumstances.
