    How does the firing pin in the S&W double action J frame series (642, 640, 442, 40, 340) work? Do these guns have a hammer or is the firing pin propelled by a spring?

    What is the weight of the trigger pull?

    How do you guys like the function of these guns compared to the shrouded hammer on the Bodyguard series?

    The hammer is smaller.
    And I have found most Smith DAO revolvers to be better than the DA on their other guns.
    UNless worked over.

    Less chance for dirt to go in.
    Although, one investigator told me his centennial got a lot of sand in it during ankle wear.
    So, maybe the bodyguard series is not much worst for dirt collection.

    Here's a picture of the hammer in a DAO J frame (Model 340).
