A conventional length golf club with a grip including a heavy counterweight, the mass of which is sufficient to cause the center of gravity of the whole golf club to be located within the boundaries of the grip. The counterweight may be an elongated member with a bore through its interior, and in order to achieve the object of placing the center of gravity within the boundaries of the grip, it must have a substantially larger cross-section than the standard-diameter shaft of a golf club. The grip may include a lower support section made of a substantially less massive material than the counterweight. In a preferred embodiment, the grip has an elliptical cross section with the major axis of the ellipse perpendicular to the face of the club head. The heavy weight of the grip, and the placement of the weight outward of the shaft, effects a substantial increase in the moment of inertia of the golf club and therefore minimizes the effects of unintended forces on the club during the putting stroke. The club can no be grasped by its center of gravity during putting, causing a balanced fulcrum hand-platform. Moreover, the large cross-section of the grip provides an ergonomic gripping surface that promotes a preferred palm grip, and in the elliptical embodiment, promotes consistently proper hand and body placement with respect to the club head, at address and during the putting stroke.
