A Freeman Swiveling Grip?
"...the handle is free to adjust itself to the position of the hand of the operator, instead of requiring as heretofore that the operator adjust his hand to the position of the barrel. Another advantage is that the handle is practically insulated from the barrel which becomes heated through repeated firing and therefore a cool grip is provided for the hand thus doing away with the necessity of wearing a glove upon the left-hand to shield it from the heat of the barrel" which "provides a suitable handgrip for firearms...to the end that they may be used with more freedom and range of movement than has heretofore been possible."
