Yep, both Gunmaster and Bullet Trap
http://www.bullettrapinc.com/ are fun places. Good staff at both and the range is good at BT. If you're feeling adventurous, SPS Guns way down Beltline to the west near Josey Ln. is one of my haunts. Closed on Mondays, though. Small and crowded with a good inventory and Larry is always good for a story. The shop dog, Mocha, is the stuff of legend.
IF you have time and a guide who knows Dallas, Ray's Hardware and Sporting Goods is like making the Pilgrimage.

Yes, there's razor ribbon on top of the building for a reason. Trust me, try to go during bright daylight hours. The reward is in the destination, not the trip.
D-Ray's at Preston Rd. and Forest Ln. in Dallas is the abridged, condensed version. Kinda like reading a 5th grader's book report on
War and Peace.
Don't forget about Bass Pro out near DFW Airport, Cabelas out nearTexas Motor SPeedway, and Cheaper Than Dirt's retail location in Ft. Worth. Of course, the 'native guide' admoinition still applies.
