Hard to say just what they made off with. Last time I was there (some years back), Don's stock ran heavily to Lorcins, Hi-Points and the less-expensive guns, usually with a bit of gold-plating here and there. Not that there's anything wrong with that.
Pop Guns, on the other side of town, experienced a similar after-hours smash and grab raid in December of 2007. I think if I owned a gun store, I'd give serious thought to a large, aggressive dog for after-hours duty...though it's probably a death sentence for the poor dog if the raiders come.
