Rossi (Think what you have is a Rossi 92) does not provide instructions on disassembly, and in the owners manual, specifically cautions NOT to attempt it. On that note, I am going to need to refer you to a gunsmith. They CAN be cleaned without taking them down- and spray cleaners like Gunscrubber can do a decent job of flushing gunk out of the action.
