Mr. Nolden, This may be a dumb question, but an older co-worker recently showed me a pristine Colt Commander in 9mm. He said he bought it at an estate auction years ago. I have tried to get information on this gun at the Colt website and others with no success. Can you tell me how old the gun could possibly be? Was it a popular model? The gun was blued with walnut grips. Very light and compact.
