It should be remembered that NICS checks are used in some states such as Kentucky, Iowa, and Michigan for CCW background checks on new and existing permit holders. Nonetheless, while NICS checks are not a direct correlation to firearm sales, they certainly do illustrate the growth trend in those sales because of their use for purchases background checks at the point-of-purchase.
