Upgrade your putter without having to change with the SuperStroke Pistol GT Tour Grip with CounterCore. The grip has been designed with a classic pistol shape with CounterCore Technology to let you fine tune your settings for the best feel and stability. The CounterCore is a 50 gram back weight that engages larger muscles in the arms and shoulders to produce a pendulum motion. This is the slimmest pistol grip from SuperStroke with the patented no taper design.
