From The Daily Beast:

More than a third of the women who participated in the National Sports Shooting Foundation’s most recent survey identified as new gun owners. This data are consistent with those of other organizations, including the National Sporting Goods Association. According to the NSGA’s Annual Sports Participation Report, the number of women who practice target shooting increased nearly 36 percent (from 4.31 million to 5.86 million) between 2004 and 2014, while the number of women participating in hunting increased 23 percent (from 2.68 million to 3.3 million). In response to a request for comment, an NRA spokesman reported tracking a 77 percent increase between 2004 and 2011 in the number of women who own firearms.
