A magazine for a firearm is described. The magazine may include a magazine housing comprising a recess at a front wall of a magazine housing top portion facing a trigger bar of the firearm. The magazine may further include a locking unit configured to move between a locked position and an unlocked position. The magazine may further include a radio-frequency identification (RFID) reader disposed in the magazine housing. The RFID reader is configured to detect presence of a wearable device in proximity to the trigger bar. The magazine may further include a control unit configured to control locking unit movement based on inputs from the RFID reader. The control unit may be configured to move the locking unit from the locked position to the unlocked position when the RFID reader detects presence of the wearable device in proximity to the trigger bar.

A signal from a wireless network and identify a parameter of the signal associated with the wireless network may be detected. A determination may be made whether to enable or disable a safety lock of a firearm in view of the parameter of the signal associated with the wireless network. Furthermore, a command may be transmitted to the safety lock of the firearm in view of the determination.

A trigger mechanism that can be used in AR-pattern firearms has a hammer, a trigger member, a disconnector, a locking member, and a three position safety selector having safe, standard semi-automatic, and forced reset semi-automatic positions. In the standard semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer such that the disconnector hook catches the hammer hook, at which time a user must manually release the trigger member to free the hammer from the disconnector to permit the hammer and trigger member to pivot to the set positions so that the user can pull the trigger member to fire the firearm. In the forced reset semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer causing the trigger member to be forced to the set position, the safety selector preventing the disconnector hook from catching the hammer hook, and thereafter when the bolt carrier reaches the substantially in-battery position the user can pull the trigger member to fire the firearm without manually releasing the trigger member. The locking member is pivotable between a first position at which the locking member mechanically blocks the trigger member from moving to the released position and a second position at which the locking member does not mechanically block the trigger member allowing the trigger member to be moved to the released position. The locking member is spring biased toward the first position and moved against the spring bias to the second position by contact from the bolt carrier during forward movement of the bolt carrier as the bolt carrier reaches a substantially in-battery position.

A magazine is provided for a firearm. The magazine comprises a locking mechanism. The locking mechanism has a user interface adapted to enable a user to select between a locked condition and an unlocked condition. The locking mechanism has a rotor movable between a first rotational position when the locking mechanism is in the locked condition and a second rotational position when the locking mechanism is in the unlocked condition. The magazine comprises an elongated shaft connected to the rotor. The magazine comprises a block element connected to the elongated shaft. The block element is adapted to move between a first position when the locking mechanism is in the locked condition in which at least one of firearm operation and magazine extraction are prevented, and a second position when the locking mechanism is in the unlocked condition in which firearm operation and magazine extraction are enabled.
