My new to me Dan Wesson ECO has had this failure 3 times in less than 200 rounds. I always try to clear jams quick as practice for real world situations so I didn’t examine it too closely, but it appears that the round is ahead of the extractor. Then it gets kinda stuck angled up into the chamber. A rap on the back of the slide will Not send it home. I’ve had to drop the mag and retract the slide and the round just drops out through the magwell. (The “almost closed” slide keeps it pinched in place. The round isn’t stuck or jammed in there. It falls free easily when I retract the slide.). This has always occurred with the last round in the magazine, but not always the same magazine. This has not occurred using the same mags and ammo in a different, compact-framed gun. I bought this gun used from another member here so I’m at least the second owner. Round count unknown but these eco recoil springs are supposed to be good for 15k rounds. Again, round count unknown but from appearance it can’t be anything close to 15k.
