So I've been thinking about it for a while and can think of the obvious points that you can conceal a handgun waaay easier than a rifle or shotgun. I never realized that it was such a big deal though until recently. So I am 19 and an obvious gun owner. I own a few rifles, shotguns, and a handgun that I recently purchased. Upon my rifle collection is a Hi-Point Carbine that is in 9mm. I went to my local sporting goods store to get some home defense slugs for my shotgun along with a 50 case of 9mm for my Hi-Point Carbine. Prior to having to buy it, I'd just get them from my friends dad who stockpiled them a few years back. He wasn't around the area for a few days, so I had to go to a local shop. So I'm going about talking to the person behind the counter and get my shells for my shotgun, and then ask for the 9mm. I go about and mention that it's for my Hi-Point Carbine, since I had read before that if you specify that it's for a rifle, you can purchase it. Not my luck. The clerk asks for my ID and I hand it to him knowing what was going to happen. He immediately gave me it back, and took my shotgun shells and told me to leave and not ever ask for handgun caliber rounds until I'm 21. Why is it that I can buy shotgun shells, which are way more lethal than a 9mm, and not purchase for my rifle when I had even stated it was for my rifle. Also, he knew that the Hi-Point Carbine was a rifle since he made a remark that he was thinking of buying one.
