I personally would not purchase from someone that requires I show my LTCH. Yeah I have one as well as an Federal Firearms Collectors license. I just don't like to see supposed supporters of the 2nd amendment adding requirements to already over regulated firearm possession laws.
I would certainly like to see some PROOF that ANYONE has been hassled or brought into court that simply sold a firearm to any citizen over 18 that was a resident of the same state - If they DIDN"T KNOW the sale was illegal! I have never seen or heard of any such issues. Granted a police officer may ask you if you did sell a firearm to XXX to aid in evidence in a case, but that certainly wouldn't get you into trouble of any kind unless the ATF or police could PROVE you knew they were not legal to possess one. Sure there are cases of straw purchases where the person selling the firearm bought it for a known felon and cases of felons being prosecuted for sales to another felon - but those don't apply to any of us (I sure hope).
I know of many people that possess firearms that do not wish to carry or obtain their LTCH. Some are regular skeet / clay shooters, some family members even some hunters. Should they be denied a FTF transaction because they didn't obtain a LTCH? By the way a LTCH could be "forged" in a matter of minutes on just about any computer with a printer and pink paper!
My feelings exactly.....
I do not forsee anyone being able to cite a example either.....
It's a feel good thing for those sellers IMHO.
