we've got 2 different conversations going on here. the op did not almost lose his entire bag so the convo about replacing dzus pins is not applicable. he almost lost his lid because the 5 little torx screws holding the hinge to the lid. they are supposed to come with a loctite patch on them, but i still add a dab myself. supposed to check them at every service....
This is what I was talking about. The screws in the lid.
