Abstract: A glue gun and a method of advancing glue sticks in a glue gun. A leading glue stick is held in a channel of a feeder assembly in an active position, and a next-in-line glue stick is positioned adjacent the active position. In response to movement of a trigger of the glue gun by a user, the feeder assembly feeding the leading glue stick in an advancing direction. Upon advancement of the leading glue stick beyond a forward end of the next-in-line glue stick, the next-in-line glue stick drops freely into the active position, and a transition from feeding the leading glue stick with the feeder assembly to feeding the next-in-line glue stick with the feeder assembly occurs exclusively by repeated trigger actuation. No other steps or actions are required to put the next-in-line glue stick into the active position upon depletion of the leading glue stick.
