  • Patent number: 9612073
    Abstract: The invention described herein improves the trigger feel and reset perception using three primary alterations. First, the addition of a spring that presses against the trigger bar, further increasing the reset action. Second, the addition of a pin or screw to a specific location on the trigger bar, increasing the deformation of the trigger bar when pushed to the side by the slide. The result is the trigger bar holds a greater force, increasing the tactility of the reset. Third, the use of a specific sear shape, altering the camming action of the sear, and thus how the sear interacts with the trigger bar and firing pin. Each of these inventions alone results in an improved trigger feel and action. Together the result is a gun with greatly improved trigger characteristics.

The computer controller (28) communicates with the authorizing device (32), and if no authorizing signal is received from the authorizing device, sends an electric output signal to the disabler (60) to prevent the fire control system from allowing the firearm to fire. The disabler, upon application of the electrical signal from the computer controller, cams the rearward moving trigger bar (52) of the fire control system clear of the hammer link (54) to disrupt the fire control system. Consequently, the firearm (10) will not fire.

  • Patent number: 6588136
    Abstract: A fire control system with a decocking lever that operates to decock the hammer and also as a safety. The fire control system also has a magazine safety to complement the decocking lever's dual functions. The magazine safety is in the “safety on” position when a magazine is not fully seated in the magazine well and in the “safety off” position when the magazine is fully seated. In one embodiment, rotating the decocking lever by lifting one of the thumb tabs applies the safety if the hammer is cocked and rotating the decocking lever in the other direction causes the sear to release the hammer but catch it before it reaches the firing pin. In an alternate embodiment, the decocking lever can be used as a safety regardless of whether the hammer is cocked or not. Further rotation lower a cocked hammer.

  • Patent number: 6560909
    Abstract: A manual safety system for reducing the chances of inadvertent discharge of a linear striker fired semi-automatic or automatic pistol equipped with the system. An otherwise conventional pistol is modified by structural changes in the trigger mechanism housing and by the addition of a trigger bar guide, a manually movable safety lever, a pressure plate and a spring. The trigger bar guide and safety lever are mounted to the trigger mechanism housing for linear and pivotal movement, respectively. A portion of the conventional trigger bar, which must be moved in order to effect firing movement of the trigger, is engaged with and blocked by the trigger bar guide which in turn is engaged and blocked by a portion of the safety lever. In order to unblock and enable the firing system, the safety lever is moved by applying pressure to a tab serving as a thumb rest.

  • Patent number: 6301815
    Abstract: A gun and a base unit such that the gun cannot be fired unless the gun comes in close contact with the base unit and the base unit determines that an authorized person is holding the gun and interfacing with the base unit. The base unit pre-records and stores characteristics of authorized persons and unauthorized person and compares these data with the person interfacing with the base unit. The gun must be gripped to be activated by the base unit and if it is put down, the gun is no longer capable of being fired. The base unit can use multiple means of identifying an individual and a process is described for combining the results from the multiple sources to determine if a person is an authorized person above a selectable threshold of probability. The base unit can also develop a probability that the person attempting to use the gun is a specified unauthorized person. Thresholds of being an authorized person or not being an unauthorized person can be adjusted.
