Hi Denise, Welcome to the forum! The number 9580 was used at least 200 times during the almost 50 years that Lugers were in production. As the others have said, we need a lot more information to be ale to help you, starting with the suffix letter, if present, located below the serial number on the front of the frame, and a description of any other markings on the gun.
Regards, Norm
