Chiappa X-Caliber 12 Gauge to 9mm Luger Gauge Adapter Insert - 7" Steel Blued

The Chiappa X-Caliber is a 9mm Luger gauge adapter insert that drops into the chamber of a 12 gauge break-action shotgun, allowing you to fire 9mm Luger pistol ammunition from your existing shotgun. The insert centers and supports the smaller 9mm cartridge inside the 12 gauge chamber so the shotgun's firing pin strikes the 9mm primer reliably.

Built from steel with a blued finish, the X-Caliber adapter measures 7 inches long with a compact profile designed to fit any standard break-action shotgun. The blued steel construction resists corrosion during repeated use, while the drop-in design allows fast, tool-free caliber changes in the field.

Ideal for survival applications, training with affordable pistol-caliber ammunition, or simply expanding the versatility of a break-action shotgun, the Chiappa X-Caliber gauge adapter insert brings Chiappa engineering to a rugged, dependable conversion tool.
