Abstract : A dual-purpose safety and retaining pin which performs the functions of safing the trigger assembly for a small arm and of securing the trigger assembly to the weapon is provided. The pin comprises a handle attached to a retainer and pin assembly which can be rotated to select safe or arm positions. The retainer and pin assembly is oriented in a specific rotational position with respect to the handle so that safing by rotating the pin can be accomplished. The pin has a can configuration whereby rotation of the pin causes the cam to move a trigger connector link into contact with a hammer sear. This action enables the weapon. When the pin is rotated to the safe position or when the pin is removed from the trigger housing, the weapon is disabled. The pin is held in position by a plunger-ball locking arrangement. The single spring used to extend the plunger also acts as a detent engaging spring for securing the rotational position of the pin.
