  • Patent number: 8601734
    Abstract: A pivoting firearm handgrip allows a user to pivot the handgrip relative to the firearm into various locked positions. The pivoting handgrip includes a grip base and a grip body that are selectively locked together by a spring biased shaft having key formations. The key formations on the shaft engage keyway formations on finger structures of the grip body. The key structures of the shaft also selectively engage locking formations on supporting structures on the grip base. A spring is captured between the head portion of the shaft and the grip body so that the key formations of the shaft are spring biased to engage the locking formations of the grip base. In use, a user depresses one end of the shaft to disengage the key formations of the shaft from the locking formations of the grip base, and then freely pivots the grip body about the base.
