Sorry to hear this about Marlin quality. I've owned their lever guns for many years. The only one I still have is a 40-year-old 39A (my second) which is a jewel. Had a fine 336 in .30-30 years ago, first-rate quality.
I always just thought the crossbolt safety was unnecessary, a case of lawyers dictating changes to a classic design--never a good thing, in my opinion.
