There's a lack of info on their site.

Who are the instructors?
What are their qualifications?
Only 6 hours?

I've been there since it's close to my office. Range is small.

I've taken a few handgun courses from Steve Moses, and he's a top notch instructor.
Also look at Tiger Valley. T.J. Pilling is also extemely good. They should be offering courses soon in Irving.
And though many don't like Len Baxley, I found him to be an excellent instructor also. He's at TDSA, and that's about 30 minutes south of downtown Dallas.
