摘要

A system for firing either a first cartridge or a second cartridge from a handgun, the first and second cartridges having dissimilar calibers. The system includes a first barrel removably mounted to the handgun, with the first barrel including a first cartridge chamber sized to permit placement of the first cartridge into the first barrel in a firing position. The first cartridge chamber is sized to prevent placement of the second cartridge into the first cartridge chamber in the firing position. A second barrel is provided, which is interchangeable with the first barrel and which is also removably mounted to the handgun. The second barrel includes a second cartridge chamber sized to permit placement of the second cartridge into the second barrel in a firing position, and the second cartridge chamber is sized to prevent placement of the first cartridge into the second cartridge chamber in the firing position.
