Had my Rossi model 351 3"reblued, and the friend that did it lost the trigger. I called th. factoy and spoke to two different people who tell me that the trigger is a restricted part and they will not ship it out that I need to ship the gun to them. I have found different Rossi Triggers on Numrich And ebay but I need to know if there are any parts interchangeability in the models. Any information is greatly appreciated thank you
