The 2008 and 2012 Olympic champion Guo, and her teammates Zhang and Zhou, executed a stable and consistent performance to finish first with a winning total of 1,146 points.
Chinese Taipei ranked second by five points, and the bronze medal went to Mongolia, who got 1,140 points.
The host South Korea placed fourth, with its team members Kim Jangmi and Jung Jeehae ranking first and second respectively to enter the individual final.
"Two of our members are young athletes, who are the first time to join this kind of comprehensive competition. Compared with the just ended World Championship in Spain earlier this month, where they performed not so well, today's performances are relatively normal," said Wang Yifu, head coach of the Chinese shooting team.
"The South Korean organising committee has purposely placed the first gold here (in the women's 10-meter air pistol event), cause one of South Korea's athletes (Kim Jangmi) comes from Incheon, who is also the Olympic gold medalist and World Cup champion. She performed very well, so it's hard for us to win this gold medal."
"The first gold of Asian Games attracts many attentions, but no matter it or other gold medals are the results of struggle. We hope every athletes could achieve their best results, and everyone has hopes (to win a gold medal)," Wang said.
