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?

Some SP-10 parts are interchangeable, some require fitting, and some aren't. I don't know which are which but my gunsmith does.

What is the problem with the firing pin? Depending one what it is, it could be as simple as a good cleaning that could fix it. If it is a spring problem, Wolff has pretty much every spring imaginable. I replaced all the springs in my Mag-10 with those in a Wolff package and the gun has run flawlessly with steel loads since.

Good information. Thanks. A local guy here was able to get it running again, I will ask him the details of what he found.
