She finished behind China's Ruijiao Pei who produced a score of 455.4 after the 45-shot final.
China's Ting Sun claimed the bronze medal, finishing with a score of 442.2.
Anjum remained in medal contention from the beginning of the final and at the end of the 15-shot kneeling position stood third behind Ruijiao and Slovakia's Ziva Dvorsak.
After the 15-shot prone series she was still in the lead.
However, after the 10th shot of the last standing series when the first two finalists out of the eight were eliminated, Anjum had gone down to the fourth position.
A brilliant 10.8 in the 41st shot took her up to second and she maintained that position finishing with scores of 10.2, 10.1, 9.5 and 10.2 to secure a well deserved silver medal.
