Japanese Type 14 Firing Pin

highbeam2004
I have noted in the literature that there are two different lengths of Type 14 Nambu firing pins. At various times one may be more available than the other. My question: are these firing pins interchangeable, or must one have the correct length pin to his particular pistol to make it functional?
Thanks.

    My advice would be to refer you to the Gunboards.com "Guns of the Rising Sun" forum. That forum IMO has the most passionate and knowledgeable base of collectors on the internet. Including several well known authorities on the field.
    They will certainly have your answer and may well be able to direct you to a parts source if you need one.

    What usually happens with the firing pin is that the very small diameter tip breaks off. This is an old fix I learned about 30 years ago from a book about 30 years old. It works very well and anyone with normal abilities can do it.

    If your tip is broken, file it flat so you can drill a hole in the center where the tip was. Find a small nail with a head on it that can be filed down so that it will fit inside the firing pin body.
    Now you can proceed two ways, by using epoxy (or equivalent) or by solder. Push the nail through so the point is sticking out the front of the firing pin and the head is against the front of the pin.
    It must be attached solidly by either the epoxy or solder or it will not work, having to have the inertia to fire the primer.
    { NOTE: The spring will push against the head of the nail but you will need the weight of the pin body or you will get misfires.)

    Once you have the tip firmly attached to the pin body, you can shape it just like the original. I always soldered mine so the tip was tempered in the process although I'm not entirely sure that it's necessary for longevity.

    NEVER THROW AWAY A BROKEN NAMBU FIRING PIN AS IT CAN BE REPAIRED VERY EASILY!!!!

    I hope this helps you and all the other Nambu owners like it does me.[:)]
