Abstract: A firearm stabilizing clip, for use with a firearm having a rear portion and body armor having a front vertical edge. The clip includes a main part having an upper jaw, a lower jaw, and a hinge between the upper jaw and lower jaw. The upper jaw and lower jaw each have a proximal end. A pair of lever rails are selectively attachable to the proximal ends of the upper jaw and lower jaw to open the main part. A stabilizing fin extends from the upper jaw and includes a broad contact surface. Once the main part is secured over the front vertical edge of the body armor, the rear portion of the firearm can rest against the broad contact surface to steady the firearm.
