There is provided an automatic firing apparatus, and a method for operating the automatic firing apparatus, the apparatus comprising a trigger actuator for automatically firing bullets contained in a magazine of a firearm; a magazine release actuator for releasing an empty magazine from the firearm; a magazine bank for storing a bullet magazine inside the firearm; and a magazine loading actuator for loading a new magazine inside the firearm from the magazine bank. There is further provided a magazine bank apparatus for use with a firearm comprising a magazine bank base having a plurality of slots adapted to receive and store bullet magazines; and a magazine load actuator adapted to be automatically triggered for loading a bullet magazine among the stored bullet magazines inside the firearm.

Trigger pull force gauge and methods of use. The trigger pull force gauge includes a housing and an arm extending therefrom. The trigger pull force gauge can include a load cell located at a distal portion of the arm spaced from the housing. The arm can be movable with respect to the housing for selectively positioning the arm in a deployed position and a stowed position with respect to the housing.

A method for determining the elapsed time after discharge of a firearm is disclosed. The method utilizes the change in induced magnetization of a firearm to obtain a value for initial magnetization after discharge of the firearm. This value can then be compared with a magnetic base calibration obtainable through further testing of the magnetization over a period of time. By comparison between the initial magnetization and the base calibration, the time of discharge of the firearm can be estimated. The invention also includes apparatus for use in measuring the magnetization of a firearm, and a kit for implementation of the disclosed method.
