Abstract: A premise-security system is disclosed combining a user-carried firearm with a remote light or lighting effect intended to be switched ON by the user who is bearing the firearm all the while the user poses a defensive posture, and causing the light/lighting effect to switch ON all while not dropping the defensive posture to a vulnerable posture, on a given self-defense occasion (eg., an after-dark home break-in home invasion by an intruder. The firearm is equipped with a manual switch module that has a switch, a power supply and wireless communications transmission circuits and components which, in response to manual activation of the switch, propagate a wireless communication or signal that causes the remote light or lighting effect to switch ON. The light and/or lighting effects are designed and disposed to provide the homeowner/resident/user to hide in darkness or shadows while brightly illuminating, dazzling, confusing and/or blinding the intruder.

Abstract: A gun includes a receiver assembly, a magazine, a trigger assembly, a sear assembly, a blowback assembly and a reciprocating slide. When the trigger rotates, the first connecting member is capable of pulling the trigger slide to move linearly, and driving the second connecting member, the sear assembly and the force-storing slide to move linearly towards the same direction. Moreover, the force-storing slide compresses the blowback spring, and the blowback slide receives a restoring force of the blowback spring to drive the reciprocating slide to move backward. The gun could achieve a simulation effect of rotating actions of the trigger, as well as a simulation effect of blowback actions of the reciprocating slide.
