Hi Jeff, Today's SXPs are designed and production is overseen by our R&D team in Morgan, Utah. They are then manufactured in our partner factory in Istanbul, Turkey.
Stay safe & have a great day!

Winchester SXP shotguns are made in Turkey by a subsidiary of the Browning Arms Company, known as the Tüfenkci Arms Company.

Hi Jeff and welcome. The inscription on the barrel always shows where a Winchester firearm is produced. This is the same factory the produces the Super X Pump (SXP). The historic factory in New Haven, Connecticut, began a tradition of quality, innovation, and extreme, hard-working versatility that has become the Winchester hallmark. Cheers and stay safe!
