A weighted grip for a golf club is disclosed. The weight is preferably a metal, such as iron and its alloys, especially steel, copper and its alloys, such as brass and bronze, tungsten and its alloys, especially tungsten, aluminum and its alloys, ceramics, including cermets, and can take the form of a cylindric shape concentric with the grip, and embedded in the moldable composition forming the grip. In other embodiments the weight can be at, or near, the extreme end of the grip. Other shapes, forms and locations of the weight are disclosed, as well as combinations of the weight with a grip formed of a moldable composition having a heavy filler therein. The combination of the grip and a golf club are also disclosed.

1. A golf club grip having a weight therein, the grip comprising: a moldable composition; the moldable composition being molded about a metallic weight;the weight being at least partially encapsulated by the moldable composition, wherein the weight surrounds a portion of a longitudinal axis of the grip;wherein the grip defines a shaft cavity for insertion therein of a golf club shaft, wherein the weight is at the extreme end of the grip, the weight overlying but spaced from an end of the shaft cavity, and not abutting any portion of the shaft cavity,wherein the weight does not extend beyond the moldable composition; and wherein the weight has at least one aperture therethrough and the molding composition extends through said aperture. 2. The grip of claim 1, wherein the weight is at least one member selected from the group consisting of iron and its alloys, tungsten and its alloys, copper and its alloys, aluminum and its alloys, ceramics and cermets. 3. The grip of claim 2, wherein the moldable composition has a density in the range of 1.1-1.8 g/cc. 4. A golf club in combination with the grip of claim 3. 5. The grip of claim 1, wherein the weight is cylindric in shape. 6. The grip of claim 1, further comprising filler particles within the moldable composition and wherein the moldable composition comprises a natural or synthetic rubber or elastomeric polymer. 7. The grip of claim 1, weighing at least 89 grams. 8. The grip of claim 1, wherein the metallic weight consists of tungsten or tungsten alloy incorporated at the extreme end of the grip, overlying but spaced from the end of the shaft cavity and the weight is completely covered by the moldable compound such that the weight is not visible. 9. The grip of claim 1, wherein the moldable composition defines the shaft cavity. 10. The grip of claim 9, wherein the moldable composition of the grip is one piece. 11. A golf club grip having a weight therein, the grip comprising: a moldable composition; the moldable composition being molded about ametallic weight, wherein the grip defines a shaft cavity for insertion therein of a golf club shaft; the weight being at least partially encapsulated by the moldable composition, wherein the weight surrounds a portion of a longitudinal axis of the grip, wherein the weight is at the end of the grip, wherein the weight is disc shaped and has apertures therein. 12. The grip of claim 11, wherein the weight is at the extreme end of the grip. 13. The grip of claim 11, wherein the metallic weight is incorporated near the end of the grip, overlying but spaced from the end of the shaft cavity, and not surrounding any portion of the shaft cavity. 14. The grip of claim 11, wherein the metallic weight is made of tungsten or tungsten alloy and incorporated at the end of the grip, overlying but spaced from the end of the shaft cavity,wherein the weight is circular disc shaped comprising a lower portion of a first diameter and a central upper portion of a second diameter, the first diameter being greater than the second diameter such that the lower portion defines a circular flange extending radially from the central upper portion,the flange has the apertures therein, wherein the apertures are uniformly placed about the axis of the weight, wherein the flange is captured by the moldable composition and the moldable composition extends through the apertures,the central upper portion extends upwardly from the circular flange through a circular opening at the upper end of the moldable composition such that a circular upper wall of the central upper portion is an exterior exposed surface visible through the circular opening and flush with the upper end of the grip moldable composition. 15. A golf club grip having a weight incorporated within the grip at the extreme end of the grip, the weight being tungsten or tungsten alloy, wherein the weight is at least partially encapsulated by a moldable composition and surrounds a portion of the longitudinal axis of the grip; wherein the grip defines a shaft cavity for insertion therein of a golf club shaft, the entire weight overlying but spaced from the end of the shaft cavity, and not abutting any portion of the shaft cavity,wherein the weight does not extend beyond the moldable composition. 16. The grip of claim 15, wherein the grip is formed of the moldable composition and the moldable composition has a density in the range of 1.1-1.8 g/cc. 17. The grip of claim 16, wherein the weight has at least one aperture therethrough and the molding composition extends through said aperture. 18. The grip of claim 17, wherein the weight has at least two apertures through which the molding composition extends. 19. The grip of claim 17, wherein the weight has at least four apertures through which the molding composition extends. 20. The grip of claim 19, wherein the apertures are uniformly placed about the axis of the weight. 21. The grip of claim 17, wherein the weight has a flange and the flange is captured by the moldable composition. 22. The grip of claim 16, wherein the grip weighs at least 89 grams. 23. A golf club in combination with the grip of claim 22. 24. A golf club grip being formed of a moldable composition having a density in the range of 1.1-1.8 g/cc having at least one weight at least partially encapsulated by the moldable composition; the weight being at least one member selected from the group consisting of iron and its alloys, tungsten and its alloys, copper and its alloys, aluminum and its alloys, ceramics and cermets; and,the weight of the grip being at least 89 grams;wherein the grip defines a shaft cavity for insertion therein of a golf club shaft, wherein the weight is at the extreme end of the grip, the entire weight overlying but spaced from the end of the shaft cavity, and not abutting any portion of the shaft cavity,wherein the weight does not extend beyond the moldable composition. 25. The grip of claim 24, wherein the weight being formed of a metal selected from tungsten and its alloys. 26. The grip of claim 24, wherein the weight has a density of at least 17 grams/cc. 27. The grip of claim 24, wherein the weight is a circular disc shaped weight having a lower portion of a first diameter and a central upper portion of a second diameter, the first diameter being greater than the second diameter such that the lower portion defines a circular flange extending radially from the central upper portion. 28.
