Looks like the tip of the firing pin is broken off! Either that or someone tried to make a replacement firing pin??

One of the ways the firing pin can get broken on a break-action gun is if the firing pin stays stuck in the forward position (doesn't retract) after firing and then when the gun is broken open it snaps off the tip of the firing pin. This can be caused by a weak or broken firing pin spring or just a bunch of crud in the firing pin channel, or possibly by the primer of an over pressure round "grabbing" the firing pin.

So what is the dropped hammer firing pin protrusion of the average break barrel?
There has to be a universal average firing pin protrusion.

To see how centered the f.p. is to the primer, knock out the primer and fill the hole with modeling clay. Once the f.p. makes a mark, that will tell you where it is hitting.
