Firing pin length

Ok so I have searched and not found any results on this subject. My question is this. Is there 3 diferent short action firing pin lengths? I know there is a standard length (7/16" bolt head) a heavy magnum (9/16" bolt head) and the crf wsm size ( 1/2" bolt head) but does the wsm use the same pin as the heavy magnum? I have a ptg heavy magnum length bolt face and am curious if the pin for the crf 1/2" is the same just needs adjusted for depth to work. I assume this is how it works but can not confirm without having the parts in front of me.
Thanks for any help.
