Abstract: Electronic trigger apparatus for use with firearms are described herein. An example electronic trigger apparatus described herein includes a trigger assembly having a trigger and trigger arm that is movable between a first position and a second position. A first biasing element biases the trigger in the first position and provides a first resistance to the trigger when the trigger moves between the first position and the second position. A switch element assembly has a spring element and a sensor operatively coupled to the spring element where the spring element provides a second resistance to the trigger as the trigger moves between a pressure-point position and the second position. The sensor detects a force or deflection imparted on the spring element by the trigger arm when the trigger is in the second position.

Abstract: Apparatus and methods are described for a weapon simulator. An example weapon simulator includes a pressure piston, which is couplable to a weapon, which acts to open a breech, and which is seated in a pressure cylinder. An example pressure piston includes a slider. The slider holds a pressure intake opening open and keeps one or more pressure outlet openings closed when the breech block is in a front-most position. In addition, the slider keeps the pressure intake opening closed and holds the one or more pressure outlet opening open when the breech block is in a rear-most position.

Abstract: Trigger apparatus for use with firearms are described herein. An example electronic trigger apparatus described herein includes a first actuation drive to move an actuation member between an initial position and an operating position at which the actuating member is to activate a trigger lever of the firearm to discharge the firearm. A clutch is movable between a first position to operatively couple the first actuation drive to the actuation member and a second position to releasably couple the first actuation drive from the actuation member. A second actuation drive is operatively coupled to the actuation member and biases the actuation member to the initial position when the first actuation drive is releasably coupled from the actuating member via the clutch.

Abstract: A firearm for firing electrically ignitable cartridges is described. An example firearm includes an electric circuit, a breech block, and a firing pin held in the breech block. The firing pin includes an ignition tip. Furthermore, the example firearm includes a contact lever, wherein movement of the contact lever is coupled to movement of the breech block. In addition, the contact lever is couplable to at least one of the electric circuit or the firing pin, and the contact lever interrupts electrical contact between the electric circuit and the firing pin when the breech block is open.

Abstract: Practice barrels for use with practice cartridges are described herein. An example practice device for use with self-loading grenade launchers includes a practice barrel having a practice cartridge chamber to receive a practice cartridge. A live cartridge does not correspond to the practice cartridge chamber. Additionally, the live cartridge is unable to be properly positioned within the practice barrel to prevent ignition of the live cartridge. Further, the practice cartridge chamber is cushioned to substantially absorb a breech energy to substantially prevent damage to the practice barrel.

Abstract: Weapons safety systems and methods of operating the system are described. An example weapons safety system in which the enabling of a weapon to shoot is controlled by means of an exchange of identification between the weapon and an enabling apparatus. An example weapon includes a weapon identification code and a safety device. An example enabling apparatus that is designed to capture the weapon identification code and to transmit an enabling signal to the safety device in the weapon includes a control unit. The control unit controls the enabling device and includes an identification memory that includes at least one registered weapon identification. Upon receiving a control signal from the enabling apparatus, the weapon transmits an identification signal that contains the weapon identification code. In addition, the enabling apparatus sends a weapon-enabling signal if the weapon identification code matches at least one of the registered weapon identification.

Abstract: Mounting devices for firearms and methods of mounting the same are disclosed. An example mounting device for use with a firearm includes a clamping device, with which the mounting device can be optionally clamped to the firearm. The clamping device includes a rigid clamping jaw arrangement, a movable clamping jaw arrangement opposite the rigid clamping jaw arrangement, and a swiveling lever. The swiveling lever is coupled to a spring device that locks the movable clamping jaw arrangement, and the spring device has a first spring arrangement, which loads the swiveling lever in an opening direction over an entire unlocking path, and a second spring arrangement, which applies a much greater spring tension than the first spring arrangement. The second spring arrangement also loads the swiveling lever via a spring travel in the opening direction and minimizes the spring travel to maintain the seat of the mounting device with respect to the firearm.

Abstract: A hammer release apparatus for a hand held firearm which reduces the force required to discharge the firearm is disclosed which includes a hammer, a pivotably mounted trigger, and a restraining lever. The restraining lever engages the cocked hammer which is biased towards a firing position by a hammer spring. The restraining lever counteracts the force of the hammer spring to reduce the pull resistance associated with the trigger of the firearm.
