The present invention relates to a firearm shooting with an open breech and comprising a detent mechanism with a hammer block (5) that can block the forward movement of movable parts (2), a trigger (10) that can lift the hammer block (5) when the movable parts (2) move backwards, an action bar (12) that actuates the hammer block (5) and the trigger (10) when shooting is triggered and stopped, and a finger piece (13) linked to the action bar (12) by a disconnector (11) that can shift from a position in which the finger piece (13) is mechanically coupled to the action bar (12) to a position in which the finger piece (13) is mechanically uncoupled from the action bar (12), the action bar (12) shifting from a shooting position to a rest position when the disconnector (11) shifts from its coupling position to its uncoupling position so as to prevent the following shot from being fired if the finger piece (13) is maintained in the shooting position.

A firearm has a frame, a barrel assembly, a slide assembly which holds a recoil assembly, and a firing system with a trigger assembly and safety mechanism. The slide and recoil assemblies are located above the barrel so that the barrel is situated between the topmost part of the frame and the bottom of the slide assembly. The barrel assembly includes a housing which is covered by the slide assembly and secures one side of the recoil assembly. The barrel can be removably connected to the frame through front and rear mounts with removable pins and can modularly connect with the frame and slide assembly so that different caliber barrels can be interchanged. In addition to the trigger, the trigger assembly has a hammer, a sear, a lever arm that engages the trigger, sear and hammer, and springs that bias the trigger assembly components.

A firearm safety system and method is described herein. The system may include a tracking system, a smart firearm and/or a smart magazine, and a smart tracking unit. The tracking system is in communication with satellites that monitor specific locations, a smart firearm and a portable electronic device. The tracking system includes an internal geographical database of specific monitored locations. The smart firearm includes a microprocessor and a receiver. The motor operates in response to a signal received, which may indicate that the firearm is approaching a no gun safety zone, whereby the signal causes the microprocessor to operate the automatic safety lock to prevent the apparatus from operating. The receiver monitors signals and receives location data from the satellites. The method of operating a smart firearm includes receiving a signal at the at least one receiver and responding to the signal by locking the automatic safety lock.

Trigger assemblies are provided for restraining a firing pin of a firearm on a selective basis. The triggers assemblies include a first and a second lever mounted for rotation within a housing. The first lever is configured to be rotated by the user, and rotation of the first lever imparts rotation to the second lever to initiate the discharge of the firearm. The trigger assemblies also include a safety mechanism having a safety lever that is movable between a first and a second angular position. The safety lever is configured to prevent movement of the first and second levers when the safety lever is in its first angular position, thereby preventing discharge of the firearm.

A firearm includes a manual safety assembly. The manual safety assembly includes a first manual safety lever that is removably attachable to a second manual safety lever. Each of the manual safety levers includes a lever portion and a connection portion that extends transversely from the lever portion. A blocking lever extends from the connection portion of the first manual safety lever so that the blocking lever is substantially parallel to the first manual lever portion. The manual safety assembly is coupled to the firearm so that the manual safety assembly may be configured in an engaged position in which the blocking lever inhibits movement of a trigger bar of the firearm to prevent the firearm from firing. The manual safety assembly may be moved into a disengaged position that allows movement of the trigger bar.

A method for inserting a safety block into a rifle comprising an upper receiver and a lower receiver, the lower receiver comprising a trigger assembly positioned within a cavity. The method includes separating the upper receiver and the lower receiver to expose the lower receiver and inserting the safety block into the cavity. The safety block comprises a hammer cavity configured to surround the trigger assembly such that the safety block surrounds at least a hammer of the trigger assembly. A hammer stop of the safety block is configured to rest against the hammer. The method includes closing the upper receiver against the lower receiver. Closing the upper receiver brings the upper receiver into contact with the safety block and rotationally pushes the hammer stop of the safety block forward and against the hammer. Rotating the safety block against the hammer rotates the hammer such that the hammer is freed from a restraining portion of the trigger assembly.

A firearm operating system includes a housing, a central pivoting member disposed within the housing, a trigger including a portion disposed within the housing and a portion extending outside the housing such that the portion of the trigger within the housing includes a hole and at least one finger that extends in a first direction from the hole. Due to movement of the trigger, the at least one finger presses against the central pivoting member to cause the central pivoting member to rotate.
