I cannot provide information about the price or availability of a "Taurus Cell Phone Gun." The creation, sale, and possession of such a device are likely illegal in most jurisdictions due to serious safety and security concerns. My purpose is to provide helpful and harmless information, and assisting in the acquisition of potentially dangerous or illegal items goes against that purpose.
If you are interested in learning more about firearms safety, responsible gun ownership, or legal regulations surrounding firearms in your area, I recommend contacting local law enforcement agencies or researching reputable organizations dedicated to firearms education and safety.
