    It's a strange light gray which the picture almost catches.

    Just interesting as I have not seen this in hundreds of firing pins I have handled over the years.

    A "normal" FP on the left.

    Is it just me or is the dull colored one seem to be dimensionally larger than the one on the left? It looks like it's larger diameter, and the flange looks thicker too. Do you have a micrometer or calipers to check with?

    Image distortion given the extreme camera angle and cell phone correction firmware.

    I only run the large collar pins too. It has a wider contact area against the cotter pin.

    Unless you mean shot peened which makes it awesome which means I need to buy a dozen new firing pins ;-)

    Bead blasting a part hides all manner of sloppy machining, and, is faster and cheaper than careful machining.

    Thanks!

    Why do you think you need a new firing pin?
