What is the result of replacing a golf grip with a heavier one?

Replacing a golf grip with a heavier one directly affects the overall weight of the club, which in turn influences the swing weight. Swing weight is the measure of how heavy a club feels during a swing and is influenced by the distribution of weight in the club itself.

When a heavier grip is installed, the balance shifts towards the grip end of the club. This increase in grip weight tends to raise the swing weight since the total weight of the club increases while the clubhead's weight remains unchanged. Consequently, the club feels heavier in the player's hands, essentially resulting in a heavier swing weight.

Understanding this, it becomes clear that the correct answer reflects the expected outcome of substituting a lighter grip for a heavier one, where the increased weight at the end of the grip leads to an overall heavier swing weight, thus impacting how the golfer perceives the club's weight during their swing.
