A friend bought a early model 5906 from me a few months back after shooting it first. The only issue was an apparent FTE. We tried new recoil springs, different mags, many types of ammo and bullet weights and the problem persisted. I figured a weak extractor spring or chipped/broken extractor. So off the gun went to S&W and after a couple of months, he heard back today that their initial diagnosis was incorrect and the gun had a cracked frame. This gun looked almost new and wasn't showing any of the typical wear a high mileage gun would have, yet S&W said it was a cracked frame. Has anyone seen a 5906 with a cracked frame?
