I am working on a older Rossi 38 special from 1986. The cylinder will not budge even if I take it all the way down. The cylinder spring in the middle isnt spring loaded like it should be. It seems that the ony way to get it off is to remove the barrel. Can I remove the barrel? Any sugestions? Also having a hard time keeping the cylinder hand against the cylinder to rotate it while cocking the hammer.. It needs to be behind a spring in the trigger it looks like.
