My first revolver was an '86 S&W 686. I've never shot aything but .357 magnum, as that's what it was designed to shoot. One problem I had was my own fault. When I disassembled for cleaning, I removed the extractor rod from the cylinder. I reassembled but did not properly torque the rod and it consequently loosened while shooting and jammed in the shroud. I could not open the cylinder. I had to remove the detent by driving out the retaining pin. It was a bear getting it out but finally did. I wrapped it with a piece of leather and tightened it and have not had a problem since. Lesson learned! The only other problem was a broken hammer nose that a local gunsmith replaced while I waited.
My wife loved shooting it so much, I bought her one for Christmas a few years ago. It has the new improved locking feature that we don't use as they are always locked in my safe. She also shoots only .357. Gotta love her! Her gun does not have a hammer nose. Uses an internal firing pin being struck by the hammer.
