The new Pistol GT Tour with CounterCore Technology is our slimmest, classic pistol shape that golfers love. CounterCore Technology lets golfers fine tune the feel and stability of the putter by adjusting the weight of the grip. Every new CounterCore putter grip comes with a 50g back-weight that engages larger muscles in the arms, shoulders and back, which results in more of a pendulum motion. The patented NO TAPER design promotes even grip pressure, which leads to better putting. It can also be played without the weight if you prefer.
