A handgun shoulder support platform includes a shoulder support stably supporting a handgun to a shooter's shoulder when shooting the handgun, thus providing greatly improved shot accuracy. A hand-engaging bracket (“perch”) on the front section matably engages and supports a shooter's hand while the shooter is grasping the grip of the handgun, but without any direct contact between the bracket and the hand gun. The bracket is L-shaped to support a backside and bottom of the shooter's hand.
