The advent of smart guns with advanced safeties and monitoring capabilities represents a quantum leap in weapon technology in addressing key problems of misuse and lack of control in actual use. This report examines the concept of a "smart gun" with fingerprint ID and live round count, including its design, functionality, and potential consequences. Fingerprint authentication ensures that only authorized users may fire it, based on biometric information to provide higher protection levels. It removes the dangers of accidental discharge or theft and makes way for personalized control that may represent law enforcement and civilian use. The built-in bullet counting mechanism monitors ammunition usage closely, calculating and giving real-time values about the number of bullets spent and remaining. This is important in tactical environments because features of this sort give users a sense of making informed judgments over critical moments. Integration takes place through microcontroller architectures and sensors that ensure this seamlessly yet do not compromise the ergonomics of the firearm. Such findings are synthesized in the review, and some light is shed on state-of-the-art studies about smart firearm technologies-that seem to include ef iciency of power, resilience to environmental influences, and tamper-proof designs as problems. Ethical and privacy issues are also considered about retaining biometric data for long periods due to historical purposes and tracking of firearms. Scalability, af ordability, and standardization shall be future key areas for attention because the innovations had their roots in artificially intelligent IoTs. It is meant to outline an envisioned future with smart gun technology that promises an increased level of safety but also responsibility and new benchmarks of handling guns responsibly
