I'm pretty sure the woman is a USPSA shooter from N. Texas that goes by Carinab on the Brian Enos forum.

Hell, they pretty much all are high ranked USPSA shooters except for the kid. Blake and JJ can just fricken rip with a pistol, and both have won their share of national events.

BTW, I haven't even seen the show. I'm going off of what happened from this thread and the HUGE thread on this show on the BE forum. The BE forum thread started when the show started looking for shooters. I don't even have cable.
