Dark,
If you can give us a little more information, we might be able to talk you through this. If you have never adjusted anything on the gun from the factory settings, we need to know that. If you have adjusted it, what caliber is it, and you need to explain how the hammer spring is frozen. Do you know if it is backed out all the way, or is it in all the way?. This info can help us in the diagnosis. Should not be a difficult task to figure out.
