I bought an single action trigger for my witness and cannot seem to get the trigger spring to fit. I called EAA and they said that I needed to take it to a gunsmith or eithe send it to them with $100 (they would NOT tell me how to do this). I am an ok self taught gunsmith and know I can do this, but I am not sure if the trigger bar needs modifying or what. If anyone has any experience with this problem please help.
