How It Works:

B.O.S. Lock integrates with your firearm's natural function to control the slide. When locked, the retention arm secures the slide in the rear position, keeping the chamber visibly empty and preventing the firing pin from reaching the ammunition, making the gun inoperable. Authorized users unlock the system with a fingerprint scan, allowing the slide to move forward, loading a round, and making the firearm operational.
