The groove the extractor slips into can be gummed up. I would spray it down with WD40 and let it soak overnight to remove any goop. The wrap some fine steel wool around a wood dowel, cleaning rod or anything you can find to fit in a drill. Then polish the cylinder with the drill. The polishing process should clean the extractor groove.

I do not shoot with my hand; I shoot with my mind. He who shoots with his hand has forgotten the face of his father.
I do not kill with my gun; I kill with my heart. He who kills with his gun has forgotten the face of his father."
