Fixing your Rossi that won't cock back
The good news is nothing may be broken at all. You don't need to remove the side plate. Some Rossi models have an adjustable tension screw. It is located on the front strap, about where your ring finger should be.when firing your revolver. Take a small screw driver and either tighten or loosen the screw. This should put the proper tension back on the mainspring.

It turned out just to be that little screw in the front strap was tightened too much.
Hope this solves you issue.:mrgreen:
