No - they are not 'trading' under the catalog - that was a different division subsequently sold, closed, and no longer running. The GM stores had an IPO in Feb. 2004 on NASDAQ and trade under GMTN.
I'm not sure how they are holding up stock-wise but their sales growth for one year is in the upper 30% range, I believe that they are the nations # 1 or 2 firearms dealers - they are watched very closely by ATF. I like their stores but if Cabelas was closer thet would win out in terms of gun-stocking and availability.
