Welcome to the forum, Anton.
You are asking about a hole in the top firing pin? It is unclear to me what you are calling the "hole". If you are asking about the grooves ground into the front shoulder of the firing pin, just behind the tip, then this would be called a "relieved" or "fluted" firing pin. These grooves were added--1914 or thereabouts, not exactly sure--and would allow the ignition gas pressure from a pierced primer to mostly pass by the firing pin instead of forcing the pin violently backward within the breech block--likely causing damage. Some also say that the grooves allow for somewhat of an accumulation of fouling before the firing pin is affected by it. Also, a qualified technician would be able to weld material onto the one with the broken tip, and re-shape/restore the tip. This might be important to do if the firing pin is matching-numbered.

This is clearly a manufacturing flaw. The internal cavity was drilled too deep or the flutes are too deep and they managed to meet, creating the hole. Although technically useable, a blown primer will probably end up shearing the firing pin retainer right out of the breach block, damaging either or both.

Greetings! I also think that this is a defect, resulting in the production. But Deputy original firing pin? or is it a copy? Can you tell from these photos. |

A TIG weld is needed, then re-grinding of the groove, only not so deep. (Compared to the groove in the pin next to it in the pic, the groove is longer, which means it was ground deeper.) Care must be taken to maintain the internal dimensions.
Your pin is numbered with at least a number 5, which appears to be of proper style font. If the number on the pin is the same as the last two digits of the serial number, it is likely original to the gun; the inspectors simply did not catch this flaw. d.p.
