Welcome to the forum ron. I share your trigger pull problems with my Model 439 and my Model 4566, except my 439 has the worst trigger pull. I hope you can get some sage advice about how to cure your problems because I could certainly use it. I also have a lot of take-up in double action pull with the Model 439 before the trigger engages. I looked back at my initial post and the only reply I received was to take my guns to a gunsmith. Hope you have better luck.
