Just experienced a few "failure to fire" at the range. The firing pin would dent the primer but it would not go off. Put the rounds in another gun, they fired OK. This started to happen a few months ago, but it is now happening more regularly.
Read somewhere that the pin should protrude .030 in out of the breech face with the hammer against the head of the pin. Is this the norm? This certainly is not the case here, I can see that the pin is just flush with the breech face when the head of the pin is pushed flat with the firing pin stop. What is the normal length for the firing pin? Can this pin be worn too short? Are there extra length pins available?
