459, 559, 659 Firing Pin(s)

[audiec01]

As I have been reading and looking for parts, I have seen references to multiple shank sizes for firing pins:


Firing Pin (.540" Center Shank, overall 2.205")
Firing Pin (.530" Center Shank, overall 2.205")
Firing Pin (.390" Center Shank, overall 2.205")
Firing Pin (.385" Center Shank, overall 2.205")
Firing Pin (.300" Center Shank, overall 2.205")


So now I have questions to what is the reason for all these different Shank sizes... and furthermore, what part of the firing do you measure to determine the shank size.
