I am attempting to find the date of manufacture for my 22-20 gauge over/under and I cannot find the serial # on it. What am I missing? The problem is that the 22 will not fire. The firing pin leaves an indentation on the rim of the shell but won't fire. The 20 gauge fires fine. Upon inspecting the firing pins while moving the selector switch it appears the 22 firing pin is shorter and beveled on one side. Is this normal for that pin?
