I went to one this weekend, and it was packed (although only about 2/3 of the floorspace of previous shows).
However, it was the biggest load of junk I'd ever seen in a room. There were nice handguns, but it was all the run-of-the-mill Glock/Taurus/Springfield/Sig stuff, nothing unique. As far as rifles, it was Fudd-Fest 2010. A dozen or so wildly overpriced Garands, plus about a billion completely boring hunting rifles.
My attitude may have been affected by my wife getting attached to the Walther P22, then declaring it was the pistol she wanted for concealed carry "because it feels the best in my hand". Then, some idiot woman butted in to claim that .22LR was a great self defense round, and that when you shot somebody with it "it just runs around in their body tearing stuff up". She of course believed the woman instead of me, because what do I know
The next table had five people trying to (no joke) sell five total guns, and one of them took ten minutes to tell my wife that the .22LR would just bounce off a leather jacket, and that he personally carried a 9mm with Golden Sabers "but I keep two Black Talons at the bottom of the mag in case they're wearing a vest". :banghead:
So yeah, they're not dying by a long shot, but I sure won't be going to the next one. Price of admission? $10 each.
