Gore turned professional in 1997. In 2005, he played on the PGA Tour after moving from the Nationwide Tour mid-season, after receiving a battlefield promotion, which is given when a player wins three Nationwide Tour events in one season.

Gore has one PGA Tour win, the 84 Lumber Classic in 2005, and is the all-time leader in career wins on what is now the Korn Ferry Tour, with seven. Gore belongs to a small group of players who have shot 59 in their careers. His historic round of 59 happened on Friday of the 2005 Cox Classic at Champions Run in Omaha, Nebraska. He is also one of two golfers to win on both the Korn Ferry Tour and PGA Tour in the same season, following Paul Stankowski in 1996.

During the third round of the 2016 Farmers Insurance Open at Torrey Pines, Gore made a double eagle on the par-5 18th hole.^[4]

After injuries and poor play, Gore went into the insurance business. In 2018, he received his license and is one of the co-founders of Kirkman Gore Insurance Services.^[5]

In March 2019, Gore was named the first executive director of player relations for the USGA.

In August 2022, Gore was hired by the PGA as Senior Vice President, Player Advisor to the Commissioner.
