A secondary trigger safety is provided in a trigger mechanism which employs first rotating member which is rotatable between a safety on position preventing firing and a safety off position enabling trigger firing. The secondary trigger safety is coaxially positioned within a formed axial passage in the first rotating member. To position the trigger in the safety off position to allow firing, both the first rotating member and the second rotating member must be turned to respective positions aligning a passage in the first rotating member with a recess in the second rotating member.

A weapon security apparatus includes a base member and a gate member pivotably coupled to the base member configured to enclose a portion of a weapon. The apparatus further includes a retractable latch, the retractable latch locking the gate member in the closed position when in a non-retracted state and releasing the gate member when in a retracted state. The apparatus also includes a solenoid configured to retract the retractable latch when activated. The apparatus includes a controller configured to activate the solenoid with a first electrical current for a first period of time during which the retractable latch moves to the retracted position and with a second electrical current for a second period of time during which the retractable latch is held in the retracted position.

Embodiments of safety selectors are disclosed. A safety selector can include a body configured to engage an internal safety mechanisms of a firearm. The safety selector can further include a first arm and a second arm that extend from the body. The first arm and the second arm can be oriented such that a non-zero angle exists between a first axis associated with the first arm and a second axis associated with the second arm.

An improvised gun lock assembly formed of two major components which alternatively slide together around a slide, trigger and/or action of a firearm, or alternatively formed by two hingedly-connected lateral halves which clamp down around the trigger, slide and/or action of a firearm. The assembly may comprise an arcuate member enveloping a barrel and action.

A selective fire firearm may be provided having a fully automatic open bolt and a semi-automatic closed bolt mode of operation. The firearm may include a trigger group having a trigger prop that ensures that, when the trigger is released in the fully automatic open bolt mode, the bolt carrier stops in an open bolt position held by an open bolt sear. The trigger prop may include a foot that, following a first trigger pull in the fully automatic open bolt mode, slides under and props a rear end of the trigger in a position that allows the open bolt sear to catch the bolt carrier when the trigger is released and propped but prevents the trigger sear from engaging the hammer.

A deterrent device communication apparatus is linked to a deterrent device. When the deterrent device is in a ready state, the communication apparatus cooperates with an intermediate communication device to establish a communication path with an emergency response center through which the holder of the deterrent device can communicate.
