The invention relates to an electronic device that is used to block the accessibility of a firearms Trigger. Wherein an electronic device is mounted on a rail or rail accessory and is locked in place using a lock and frame allowing the device to fit an array of firearms. The lock and frame are in place to stop easy removal unless the possessor has the key to remove them. The device its self uses a battery to operate and picks up a transmission broadcasted from a Bluetooth within its programmed range by the use of a Bluetooth proximity detector. Once the transmission has been picked up it activates its locking mechanism in the form of a solenoid causing its pin to shift and allows a slide placed in front of the trigger acting as a second trigger to move back and forth allowing the movement of the firearms trigger. The slide is moved back into its original position by the use of a spring. When the Bluetooth is out of the device's proximity detectors programmed range, the solenoid returns to its locked state stopping access to the trigger. Making the trigger locking device a beneficial reusable safety device.

The invention is aimed at improving the accuracy of shooting by reducing the force on a trigger of a firearm during firing. The technical result is achieved by the fact that the design of the trigger mechanism includes a housing in which a hammer and a hammer spring are installed, a tubular axle on which the trigger having a groove allowing longitudinal movement along the axle is installed, thereby disengaging a return mechanism installed in its housing, a roller sear, and a single-fire sear. To engage the return mechanism, the trigger and the hammer are equipped with cams, and when a breechblock carrier is recoiled, the hammer is lowered and its cam affects the trigger cam, forcing the trigger to move backwards (if it has been moved to a forward position before). The return mechanism is also engaged when a safety lock is activated.
