A universal percussion trigger mechanism, comprising a trigger housing (22) with a magazine (1), safety catch (3), magazine latch (7), firing pin (8), trigger bar (23), spring (12) of the trigger bar, universal percussion mechanism (38), which is fixed in the receiver (20), and consists of a bracket for universal percussion mechanism (16), cocking piece (17) with a cocking indicator mounted on the axis of the cocking piece (18) and spiral mainsprings (19), sear (11) and a single-shot sear (27).

An ammunition monitoring apparatus of the present disclosure includes at least one object-position detection sensor and a controller. The at least one object-position detection sensor is installed near a shell or charge route to face at least one set area and to output position information of each shell or charge in the at least one set area. The controller is configured to determine whether a position range occupied by the shell or the charge in the at least one set area exceeds an allowable position range, based on the position information received from the at least one object-position detection sensor, and to output an alert signal indicating a poor position upon determining that the position range occupied by the shell or the charge in the at least one set area exceeds the allowable position range.

A dry-fire magazine for use with a firearm is disclosed. The dry-fire magazine includes a controller and a plurality of sensors connected to the controller. The dry-fire magazine uses the plurality of sensors for collecting data associated with one or more operations of the firearm and thereafter the data is transmitted, using a communication unit embedded within the controller, to an end-point device such as a smartphone.

A firearm has a barrel, a trigger, a bolt assembly and a magazine well with a longitudinal direction, in which a magazine is movably accommodated in the longitudinal direction. A manually actuable slide is movable substantially transversely to the longitudinal direction. The slide engages on a driver connected to the magazine and moves the driver with the magazine from a safety position into a feed position.

The present invention is an ammunition magazine utilizing slide lock release relief depressions made to fit around a firearm slide lock release lever. The magazine body can further comprise trigger bar relief and frame relief depressions configured to fit around the corresponding components of a firearm, permitting the function of firearm components while maximizing the thickness of the firearm magazine body material.

An auto-releasing method and arrangement of a detachable magazine for a firearm is provided. The auto-releasing arrangement is able to physically remind the operator that it is the right time to replace the magazine and to continue fire without having to performing a series of magazine reloading operations to reset the firearm into the fire mode, wherein the magazine will automatically be released and removed from the magazine receiving cavity of the firearm. In other words, the operator can simply insert another loaded magazine into the magazine receiving cavity while the firearm still has at least one cartridge chambered for firing, so that the time cost on performing such operations can substantially be saved to increase the survival probability during a gunfight or the like.
