I was stationed at Laughlin for 6 years (kill me.)
I don't know if he still does it, but you can look up James Tackett with Cactus Country Handgun Training. He has his own private range near Ruben Chavira elementary school, and usually holds a steel match once a month. Hell I still have his phone number.
He also boards dogs and cats! Look him up if you need your animals boarded. He's good people.
Another club is in Brackettville at Fort Clark Springs. It's rather nice, and they hold IPSC events there as well.
