First up, the Pistol, has a notch in the back of the grip, under your non-dominant hand, that places your non-dominant hand on a different plane than your dominant hand. Well, what does that mean? That means it allows your hands to naturally flow open, closed. So if you have an open, closed putting stroke with slight to extreme arc, this is the perfect grip for you.
Our second putter grip, the Paddle, is like the non-taper round grips on the market today, except it has a slight amount of taper and a small flat section on top for you to put your thumbs. It allows your hands to flow straight back, straight through. That’s our two putter grip shapes, the Pistol, and the Paddle. So if you have any kind of arc in your putter stroke, use the Pistol, and if you have a slight arc to no arc in your putter stroke, use the Paddle.
