The Burnet show was good for me at least. I bought two S&W 3rd Gen magazines at silly low prices. One seller had no idea what it went to, but my eye can pick them out in a crowed. The other seller was an FFL and he told me that he bought out the inventory of a shop that closed. He was selling a bin of various magazines for $20.00 and I found an an ultra rare 3rd Gen magazine.
I also enjoyed looking at all of the guns not available in MA. That included two brand new stripped AR lowers that ironically are made there, but can't be sold there.
The guns I saw were mostly at the higher end of the price range. One vendor was ranting about no one wanting to buy guns. I didn't engage him in a useless debate and I understand that setting up at a gun show involves expenses that need to be recouped. Still when I see a gun listed at or above MSRP I'm not surprised that buyer interest is low.
