Channel 6 News in Wichita Fall, Texas reports:

Handgun sales numbers are up, but it’s who’s buying them that may be surprising. National numbers show that women are quickly becoming some of the top customers at gun shops.
Certified handgun instructor Kathy Richardson said, “I’ve had more women in this past year than I have in the past years before.”
This isn’t just in Richardson’s class.  Enrollment numbers are up nationwide.  The National Shooting Sports Foundation shows gun stores reported a 73 percent increase in female customers. . . .
