Claim:
1. A hybrid primer device for use within a cartridge having a longitudinal axis and a propellant charged disposed therein, comprising: an insulated base; an electrical primer comprising at least one pair of electrode pins, wherein said at least one pair of electrode pins comprises an anode and a cathode, wherein first ends of said anode and said cathode are fixedly mounted within said insulated base and are spaced apart from each other so as to be electrically insulated from each other and yet are adapted to be connected to a power source, wherein second opposite ends of said anode and said cathode are disposed a predetermined distance from each other so as to generate an arc spark between said anode and said cathode when electrical power is supplied to said anode and said cathode, and wherein said anode and said cathode extend substantially axially away from said insulated base for a predetermined axial distance, substantially parallel to the longitudinal axis of the cartridge, such that the spark can be generated at a predetermined distance along the axial extent of the cartridge and at a predetermined distance from said insulated base; a chemical percussion primer housed within a percussion cap, wherein said percussion cap is disposed within said insulated base and is adapted to generate another spark as a result of a mechanical strike being imparted to said percussion cap; and at least one flash hole defined within said percussion cap so as to permit said spark, generated from said chemical percussion primer housed within said percussion cap as a result of the mechanical strike imparted to said percussion cap, to propagate into the cartridge, within which the propellant charge is disposed, such that the propellant charge, disposed within the cartridge, can be ignited by both of the sparks generated by said at least one anode and said at least one cathode of said electrical primer, and said mechanical strike imparted to said percussion cap.
