870 bolt - firing pin/spring question ('55 Wingmaster)

    I have a '55 Wingmaster with a broken firing pin. I ordered a new pin and spring from Numrich and it is here in front of me.
    When comparing the old combo to the new, I find this:

    1. The new firing pin has a longer area for the spring. The seat for the spring is further towards the rear of the gun.

    2. The new spring is a little shorter than the original spring.

    3. The firing pins are the same length.

    If I put the bolt together with the new pin and spring, the pin is very softly sprung due to the combination of a longer area and shorter spring. If I use the new pin and the original srping, it is stiff. It is moveable and looks like it will strike a primer but I am leary of mixing the parts.

    Is there a concern for a firing pin spring that is too soft?

    Does this make sense?

    I will only say what I would try, since I don't want to give advice that could create a problem. I would try the stiff spring and test the gun to see if it works OK. I think it probably would.

    I don't see anything in the GPC book about there being any change in those pins nor do I recall any. You might call or write to Remington and order parts from them, giving the serial number of the gun; they would know if there were changes where GPC might not. You can always return the parts to GPC if they have not been used.
