Just went to a TX gun show and it was just fine. There was a wide selection of new guns and quite a few used. Gun prices can be better than the local best priced big box stores by a few tens of dollars.
Ammo isn't that hot a deal. Saw some new fun things like a Chiappa revolver and the Keltec double magazine shotgun and 30 round 22 mag semi pistol. Lots of ARs to look at and compare.
Best was that I took a Colt revolver that I bought a few years ago for 350 and got offers of 600. Back into the safe for a bit. No need to sell that nice profit yet.
I've seen crappy gun shows in FL though.
