No, the Ruger P89 is designed specifically for 9mm cartridges and cannot be converted to shoot .40 or .45 caliber ammunition. While some firearms can be modified to accommodate different calibers, the P89's design and construction do not support such conversions. Attempting to modify the firearm in this way could lead to safety issues and malfunctions. If you're looking for a different caliber, it's best to purchase a firearm specifically designed for that caliber.
