The 33-year-old Iranian, who also claimed the P2 10m air pistol women's SH1 title at the Paralympic Games two years ago, triumphed with a total of 220.6 points.
China's Huang Xing finished second with 215.6 points, while compatriot Lou Xiaolong came third with 194.6.

It also marks the inaugural combined World Cup event across the three shooting disciplines.
