Remington Model 12, pump .22lr. Firing pin/ejector is flat and has a slot that one pin is centered and has a return spring captured. The other keeps the firing pin/ejector "guided". The guiding pin is the one I can see falling in the trigger assembly.
Drilling and inserting a larger pin involves machining the slot that has the captured spring also.
Rough image of firing pin/ejector. One pin goes through slot, the other pin is in the "cut-out" area.
