Abstract: A firearm mounted video camera system that is intended for civilians, law enforcement, and military professionals to generate tangible evidence for examination of firearm shooting related incidents. A mounting frame has a pressure switch grip assembly, a trigger guard cover assembly, a trigger guard side plate assembly, and an audio-visual rail. In addition, the firearm mounted video camera system has an audio-visual recording assembly. The audio-visual recording assembly mounts onto the audio-visual rail. The audio-visual recording assembly has recording means to record audio and/or video recordings of a target and/or surrounding area when a pressure switch of the pressure switch grip assembly is activated. The pressure switch grip assembly comprises a bottom edge, a top end, an exterior face, and an interior face. A pressure switch is cooperatively mounted within the pressure switch grip assembly. The pressure switch grip assembly mounts onto a grip of a firearm.
