Chiappa Firearms 12GA 9mm Caliber Conversion Kit. This conversion is made possible by using a 9mm Luger cartridge in the chamber normally used for small arms or home defense purposes and a 12 Gauge cartridge for range safety or varmint hunting. The conversion therefore gives the shooter a narrower barrel with longer shot path resulting in a more accurate shooting experience. This is a very popular and versatile unit widely used by the Italian Police Force for training purposes as an extra forearm for export to Russia and for home defense purposes in case of small arms fire. Due to the very simple construction this insert will give the shooter a very long service life. This is due to the very precise manufacturing - no part of the insert is left over which is an empty chamber. When the cartridge chamber is pushed out of the gun the impact force is absorbed by the bolt and not the frame or locking mechanism. As such serious damage can result if an X-Caliber is not actuated.
