Hudson's big problem is that they were trying to sell a new gun for a high price in a market where most of the money is to be had in selling injection-molded tactical tupperware, so they're likely to never be more than a niche company pitching to the cool-gun hipster crowd.
Couple the niche market for their product with the difficulty of bringing an entirely new gun design to market, and it's pretty clear the odds were always going to be against them, even with all of the good will generated for them in the press and online.
