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.

A locking gun mount provides a top frame and a bottom frame coupled by a shaft tube with a spring that pushes the top and bottom frames apart. The locking gun mount also includes a locking mechanism that also functions to open and close the locking gun mount. Also included is a back plate coupling a lag bolt for securing the locking gun mount to a wall.

The techniques described herein relate to methods and apparatus for firearm safety mechanisms, visual safety indicators, and related techniques. A firearm includes a handle comprising one or more buttons disposed at least partially within a surface of the handle, such that the one or more buttons can be in contact with an operator's hand when the operator grasps the handle; a safety mechanism in mechanical communication with the trigger. The safety mechanism comprises: a first position that blocks actuation of the trigger; and a second position that does not block actuation of the trigger; and at least one processor configured to: upon determining an input code matches a stored code, transmits a signal to the safety mechanism to change the safety mechanism from the first position to the second position so that the firearm can be fired by the operator.

A gun safety lock uses a turnbuckle mechanism and a locking mechanism to lock a breach end of the turnbuckle mechanism in the breach of a gun and lock a barrel end of the turnbuckle mechanism in a barrel of the gun. The gun safety lock is removed from the gun by unlocking the locking mechanism to allow the turnbuckle mechanism to be rotated so that its breach and barrel ends can be removed from the gun.

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.
