I recently received a Model 989 which jammed frequently. When jamming, the spent shell is frequently stuck cross ways above the loading cartridge. I opened it up and the internals were filthy. I cleaned it up well but the problem did not improve. I opened it up again and removed and cleaned both extractors. The extractors looked good and the springs were not distorted or broken. The left extractor spring was much softer than the right. The only part that appears broken is the hammer but the I have no misfires so I don't think the loss of metal is important. The gun will jam when I load it single shot and remove the clip so I think it has to be related to the extractors. Has anyone had this problem? Thanks!
