Provided herein is a laser sight trigger guard for a handgun that enables a user to simultaneously switch on a laser as the trigger guard is moved before firing. The trigger guard has a first component that houses a laser assembly and a second component that covers the trigger when the handgun is not in use. The second component is pivotably attached to the first component. The laser assembly has a laser unit, an on off switch and a power supply. When unpivoted, the second component covers the trigger and the laser is kept in an off state. When pivoted, the second component no longer covers the trigger enabling the laser to switch on and to simultaneously provide access to the trigger.
