I don't think that will be the case. I have conversed with the folks at International Leather Club regarding things such as holsters, sheaths, cigar humidors, and "right to bear arms" key chains. No issues. I am sure rifle slings will be no issue as well.
so far, it has been fairly easy to get the site up and running. More to come on sales. I guess the one thing that will be advantageous is that folks looking here will be looking for high quality items, not junk. I hate selling on FB. Everyone wants to pay pennies on the dollar for good quality stuff. Not worth my time.
