This time last year, Nicole Tan was not even a competitive marksman.
No wonder, she said, it was "a crazy, unbelievable feeling to make history" following her triumph in the SEA Games women's 25m pistol final on Tuesday.
The former army infantry officer had decided to give it a shot after winning several inter-formation tournaments.
"At this SEA Games, I didn't expect much from myself because the team award was more important to me - now, I have a gold and a silver, wow," she said.
The 23-year-old had also teamed up with Teh Xiu Hong and Teo Shun Xie for silver in the team women's 25m pistol (rapid fire) event.
They scored 1,699 points, seven behind champions Vietnam.
Tan beat Malaysia's Siti Nur Mastiah 9-7 to claim the Republic's first and only shooting gold medal at the ongoing SEA Games.
Vietnam's Trieu Thi Hoa Hong was third.
But it was not all smooth firing for Tan at Yangon's North Dagon Shooting Range.
