So, as I recently mentioned on the thread regarding 10 gauges, I have a Ithaca Mag 10. It originally had the 30 inch, full choke barrel but I had ordered a new 26 inch barrel with screw in chokes from Ithaca. Anyway, in the good blind today I had a problem with the firing pin. Anyone know if parts can be ordered from Ithaca? I sent a email to the service department but have not heard back yet. Alternatively, are the parts from the Remington SP10 interchangeable?
