Selling Accesories at Gun Shows

I would like some opinions on this and maybe some ideas. I am considering selling gun accessories at Gun Shows. I am thinking my initial investment will be $1000.00. So I am going cheap. I am thinking of starting with NCStar products. I contacted them and its pretty easy to get started with just a license (Do you even need a license for gun shows) and a contract. They will do a thousand a month no problem. Actually even way less. I have heard several people on here say its not the guns at gun shows that make money, its the accessories. So is there money to be made? If you had $1000 startup what would you buy to resell? What would you do different than what I am thinking of doing?

Thanks
