A location-based gun magazine has a housing having a plurality of locking apertures, a spring, a wireless receiver switching device, a battery, and an electromagnet locking mechanism. The electromagnet locking mechanism has a locking tab for engaging and locking with the plurality of locking apertures, the locking tab actuatable via the electromagnet, the electromagnet receiving a signal from the wireless receiver switching device. The wireless receiver switching device may have a radio receiver, a GPS chip, or other device for receiving location-based information.

A frame of a pistol includes a handgrip portion, an upper frame portion, and a trigger guard. The handgrip portion defines a magazine well for accommodating a magazine. The upper frame portion is connected to the handgrip portion, and includes a barrel-receiving section having a bottom wall, two sidewalls extending upwardly and respectively from two opposite ends of the bottom wall, two through slots respectively formed in the sidewalls, a compression spring retaining groove formed in the bottom wall, and a spring plate retaining groove extending forwardly from the compression spring retaining groove. The trigger guard is connected to and is disposed between the handgrip portion and the upper frame portion.

A simulated magazine useful to provide for simulated firing of a firearm includes a cycling lever arm which is depressed once every time the firearm is cycled; a linearly shaped counting plunger; a plunger spring biasing the plunger in an upward position; and a spring assembly connected to the cycling lever arm and acting upon the plunger. Depression of the cycling lever arm causes the plunger to move incrementally upward. When the plunger is in a fully up state, a slide catch trigger extends upward from the magazine, the slide catch trigger causing a slide of the firearm to remain in a back, open state.

A system that enables a user to simulate the reloading of a magazine fed hand operated device used in a simulation. The user may eject the physical magazine using the magazine ejection button on the hand operated device, and then engage that same magazine which has been stopped from being fully ejected from the hand operated device's magazine housing by a magazine retention mechanism. An internal magazine engagement sensor registers with the simulation that the magazine has been ejected by the user and then has been re-engaged when the magazine is fed back into the housing and locked in by the hand operated device's locking mechanism.

A pistol device includes a handgrip portion having a grip body defining an accommodation space, a snap hole extending through a front side of the grip body, and two positioning holes extending through left and right sides of the grip body. The snap and positioning holes communicate with the accommodation space. A magazine base is detachably disposed on a bottom end of the handgrip portion, and includes a surrounding wall, a snap block detachably engageable with the snap hole, and a connecting portion connected to the surrounding wall and having at least one pin hole extending therethrough. A positioning pin is detachably inserted through the positioning holes and the pin hole to fix the magazine base to the handgrip portion.

A crowd control projectile includes a payload carrier, an incapacitating agent inside the payload carrier, and an activating mechanism for activating the incapacitating agent. The activating mechanism includes a sensor and a timer. The timer delays the activation until a predetermined delay after the sensor senses that the projectile has been launched. Alternatively, the activating mechanism includes a receiver for receiving an activation signal after the projectile has been launched. Preferably, the projectile has the shape of a clay pigeon. A launcher of such a projectile includes a communication mechanism for transmitting a timing signal or an activation signal to the projectile and an arm for launching the projectile by direct contact. To control a crowd, the projectile is launched over the crowd by direct contact with a solid arm and the activating mechanism is used to activate the incapacitating agent when the projectile is above the crowd.
