Abstract

A programmable gun has a body supporting a handle, a trigger and a pin actuatable between a first position providing for a trigger depression to fire a bullet and a second position restraining the trigger depression. A memory stores a print identifying an authorized person's hand when such person inserts a key in the handle and then grips the handle. Hand prints of one (1) or more authorized persons, or several hand prints of one (1) person, may be stored in the memory when such persons move the key, after insertion, to individual positions and then grip the handle. When an authorized person thereafter grips the handle, that person's hand generates a print for comparison with the prints in the memory. A comparison coincidence produces a pin actuation to the first position. A subsequent gun firing is recorded in the memory as to time and as to the authorized person. When a comparison coincidence is established, the ability to fire the gun continues until such authorized person relinquishes the gun. If the authorized person relinquishes the gun before firing, the pin becomes actuated to the second position after a particular time period. If the authorized person again grips the handle during such particular time period, the time period is re-initiated. When an unauthorized person grips the handle, no comparison coincidence occurs and the pin is not actuated to the first position. A print of such unauthorized person's hand and the recording time are recorded in the memory.
