A golf club, such as a putter, utilizes removable shafts, removable weights in the shaft grip end, a variable length adapter to connect the shaft to the putter head and vary the shaft end weight, and removable weights in the putter head to vary the pressure of the putter relative to the putting surface speed. The putter head also includes weighted inserts or plugs placed in the head during manufacturing to vary the weight of the putter head. The striking face has an additional insert at the striking point adapted to receive various types of plugs to vary the percussion response. Grooves on the top surface of the club head provide improved "sighting" of the golf ball in relation to the hole. The club head shape and grip end appearance remain unaltered and thereby retain user familiarity and confidence.
