Firing pin spring

Posted by Carl Archut Sr on Sunday, 11 October 2020, at 4:16 p.m.

Could anyone tell me the correct length of the firing pin spring for an 1870 50 caliber Trapdoor Would it be the same as a 4570 The spring which is on it now seems short as it doesnt push the head of the pin out of the breech block. I had an extra 4570 spring that I installed and it works as intended. Just wondering if there is a difference.
