Abstract: A trigger system includes a jaw latch coupled to an inner surface of a first jaw member of a pair of jaws of a coil-spring trap, the jaw latch defining a ledge. A jaw dog includes a body portion having an elongate linear configuration and opposed proximal and distal ends, the proximal end including a latch flange selectively positioned on the ledge at a set configuration. A pan has a continuous peripheral edge and a cam member extending downwardly from the peripheral edge, the pan defining a planar configuration that is perfectly horizontal at the set configuration. The body portion defines a cam ridge configured to partially receive the cam member at the set configuration. The trigger system is fired when pressure is detected at any point on the pan surface.
