A firearm trigger lock assembly for inhibiting a firearm from being fired includes a sleeve that can be positioned around a grip of a firearm. A wedge is coupled to the sleeve thereby facilitating the wedge to be positioned behind a trigger of the firearm when the sleeve is positioned around the grip. A locking unit is coupled to the sleeve and the wedge is removably engaged to the locking unit. The wedge is locked behind the trigger when the locking unit is turned on to inhibit the firearm from being fired. Conversely, the wedge is removable from behind the trigger when the locking unit is turned off to facilitate the firearm to be fired.

A removable firearm chamber-obstruction mechanism includes a locking mechanism including at portion configured to be inserted in a chamber of a firearm and engage the chamber so as to be locked in place. The locking mechanism includes one or more finger actuators, a thumb bar actuator engaged with the one or more finger actuators, a release key connected to the thumb bar actuator, and a tooth key disposed in abutment against the release key. A handle covers the locking mechanism, and a lid encloses the handle. The locking mechanism locks and unlocks the tooth key upon a successful manual actuation of the one or more finger actuators and the thumb bar actuator, such that the tooth key engages the chamber in a locked position and is unengaged from the chamber in an unlocked position.

A trigger lock for a trigger of a firearm, components thereof, and associated methods. The trigger lock comprises a first guard including a bolt having a catch. The trigger lock includes a second guard comprising a bolt receiver configured to receive the bolt to connect the first and second guards with the trigger between the first and second guards for obstructing access to the trigger. The bolt receiver includes a keeper arranged to engage the catch when the bolt is in the bolt receiver to maintain the first and second guards connected to each other. The second guard includes a shield overlying the bolt receiver and configured to obstruct cutting of the bolt receiver to disengage the keeper from the at least one catch.

Described herein is a physical interlocking rifle or gun magazine that temporarily incapacitates the weapon but allows the owner to quickly remove the safety magazine and insert a usable magazine with live ammunition to respond to an emergency situation. In one example embodiment, the safety magazine includes a biometric actuator that identifies an authorized user of the weapon and immediately disengages that interlocking mechanism in the safety magazine to allow its prompt removal and replacement with an operative magazine.

A gun lock has a user manipulatable proximate end and a distal end for insertion into a barrel of a firearm. The distal end is spaced from the proximate end by a distance sufficient to allow the distal end to enter the chamber of the firearm when the proximate end is adjacent to but spaced from the barrel of the firearm. The distal end has elements which respond to user manipulation to transit from a first state allowing the distal end to enter and withdraw from the chamber of the firearm and a second state which prevents the distal end from withdrawing from the chamber. With the distal end of the gun lock inserted into the chamber and then transiting to the second state the inability to withdraw the gun lock from the firearm prevents the firearm from normal use.
