1. A system for restricting access to a firearm trigger of a weapon having an accessory rail, said system comprising:
a stationary sheath having a central enclosure that is defined by a forward facing end, a backward facing end, a top end, a bottom end, and an outside surface,
said stationary sheath further including a pair of protrusions that are disposed along the top end thereof, said protrusions being configured to removably engage the accessory rail of the weapon, so as to position the backward facing end of the stationary sheath at a location adjacent to the firearm trigger;
a unitary and generally U-shaped non-stationary sheath that is in communication with the backward facing end of the stationary sheath;
a rechargeable and portable power source that is positioned within the central enclosure of the stationary sheath;
a user input component that is positioned along the outside surface of the stationary sheath; and
an electromechanical drive system that is positioned within the central enclosure of the stationary sheath, said drive system being in communication with each of the user input component, the power source and the non-stationary sheath, and is configured to selectively transition the non-stationary sheath between at least one of a deployed position and a retracted position upon receiving an instruction from the user input component,
the electromechanical drive system comprising:
a motor;
a lead screw that is in communication with the motor; and
an elongated threaded shaft this is positioned centrally along a longitudinal axis of the non-stationary sheath, said threaded shaft being connected to each of the lead screw and the unitary and generally U-shaped non-stationary sheath,
wherein the threaded shaft is configured to receive a rotational force from the lead screw and to impart a linear force onto a center portion of the generally U-shaped non-stationary sheath; and
wherein in the retracted position, the non-stationary sheath is positioned within the central enclosure of the stationary sheath, and in the deployed position, the non-stationary sheath extends outward from the backward facing end of the stationary sheath and is configured to fully enshroud the firearm trigger of the weapon.
