I've never owned one. Have had to work on customers', though. Based on that experience I don't really want one. Prefer 9422s or Marlin 39s. They are a pain to reassemble. If you insist on taking one apart fairly often, keep an extra ejector spring on hand. Firing pins do break. The lower receiver is diecast alloy, I've seen a couple with the steel pin that engages the upper receiver broken loose.
Good points - nicely finished, shoot well, slick short throw action.
