I have 3 Pedersoli's. They are top quality guns. You can get service at several places in the U.S. . here's a quote from their company profile page :"Pedersoli's guns are covered by two years warranty from the purchase date for the mechanical parts. The spare parts are distributed in all the world by the various distributors, while Service Points in USA and Europe handle the warranty and non-warranty repairs."
I returned a Pedersoli to exchange for a different caliber to Dixie gun works without a problem. Cabelas is the same way . Cherry's is also a distributor. Parts are readily available through many shops like TOTW etc.
