This invention is to a wireless dual module system for sensing and indicating the remaining rounds contained within a detachable or integrated firearm magazine. The dual module system, one containing a display (display module) and one more round sensing modules (magazine module) may be implemented with no significant modifications to the firearm or magazine. The display module and one or more magazine modules wirelessly linked together are referred to as the system. The system is configured to provide the number of rounds remaining in a magazine, if a magazine is seated properly in the magazine, to indicate an empty magazine, or to indicate that the number of rounds remaining in the magazine is above or below a predetermined range. The system is able to provide an immediate indication of the remaining rounds in a magazine, regardless of the amount of rounds discharged or supplemented by the user.

The dual magazine pouches allows one of the two magazines to be partially ejected from the pouch automatically when the pouch is opened so that a shooter has quick and easy access to the magazine yet the remaining magazine is retained securely within the pouch. The pouches include a main body formed by a cargo pocket sewn to a back / flap, which extends above the cargo pocket and folds over to enclose the open mouth of the pouch, and an “elevator” mechanism, which automatically raises one of the magazine when the pouch is opened. The “elevator” mechanism is provided by two elastic members: an elastic retention band and an elastic “elevator” band or cord. The retention band snugly holds a first ammunition magazine against the back / flap when fully inserted into the pouch. The elevator band forms a “saddle” within which a second ammunition magazine sits. Fully inserting the second magazine stretches the elevator band. When both ammunition magazines are fully inserted into the pouch, the back / flap is folded over the tops of the magazines and secured by hook and loop patches. When the back / flap is lifted, the tension from the elevator band automatically lifts the second magazine partially ejecting it from the pouch above the exposed top of the first magazine.

The invention is a handgun in which the spring-loaded slide is replaced by an electric motor, engageable only upon an authorized user entering an access code. A combination rechargeable battery and keypad engages the butt of the handle where the magazine well is located and includes an electrical plug the fits into the handle, making an electrical connection between the battery and a microprocessor in the handgun. Entering the proper code on the keypad allows the microprocessor to complete the circuit between the battery and a motor that actuates the slide. When the device is not in use, the magazine having been removed, the motor then moves the slide rearward, ejecting any cartridge in the chamber, and maintains the slide in a position where the chamber is always open, thereby making obvious to anyone that the gun is not loaded.

A rotary magazine for a firearm includes a hold-open lever that is actuated after the last shot is fired to hold the bolt in an open condition to signify that the magazine is empty. No modification to the firing mechanism, bolt or other part of the firearm is required. The hold-open lever is tripped to a hold open position by a stud or similar trip mechanism mounted to the magazine's rotor. The rotor and the magazine's feed insert are formed in a manner such that the rotor rotates an additional amount beyond its nominal original position (magazine empty), without interference from the feed insert or other structures in the magazine. When this additional rotation occurs, the trip mechanism on the rotor actuates the lever, moving it to a position in which it blocks the forward movement of the bolt. Several different arrangements for a rotary magazine with the hold open feature are described.
