To me, Loftis Gun and Pawn is one of the best games in town. They have some very good prices and they don't brow-beat you if you are not selecting their preferred pistol/rifle/shotgun etc.
I am in no way affiliated with them except by being a very satisfied customer. YMMV.
By the way, they are on the corner of Sunshine and Campbell. Across Sunshine from Bass Pro shops.
