1. An additive manufacturing enhanced sidearm comprising:
an ejectable barrel group assembly having two barrels, each with a chamber, in an under and over configuration thereby forming a top and bottom, and preloaded with keyed rounds each having a series of circumferential keyways,
wherein each of said projectiles is keyed via a keyway in a chamber in said barrel,
each of said projectiles in said barrel group is keyed having 0 to 4 keyways formed in the side of the projectile,
said projectiles having a propellant and primer means disposed behind said projectile in said chamber,
a series of electrical contacts disposed within said chambers in communication with said primer means,
a rail disposed at the bottom of the barrels with a locking notch means,
a battery disposed within said ejectable barrel group,
a grip assembly in communication with said ejectable barrel group assembly,
said grip assembly comprising:
a hand grip,
a circuit board disposed within said hand grip,
a trigger group disposed upon said circuit board,
a high voltage generator circuit disposed on said circuit board,
at least one recoil plate assembly disposed upon said circuit board,
at least one microprocessor disposed upon said circuit board, and
a removable safety block that interferes with the battery-to-circuit board connection.
