The fact that all the “from my cold, dead hands” people are buying lots of short barreled rifles and suppressors, both of which take fingerprints and puts you on a government list, just because the $200 tax went away is a bit concerning to me.
Personally, just like the smart ID is a red line and I just won’t fly anymore because I don’t have one unless I get a passport, I don’t care how nifty a suppressor is, I am not getting fingerprinted and put on a government ownership list just to use one.
Constitutional carry is a recent development so their fingerprints are likely already on file from concealed carry permits. If you have ever purchased a gun from a store your 4473 was filed away in a database so you're already on the list of gun owners.
You can pay an extra fee if you don't have a REAL ID to fly, but you still have to go through the airport where your biometric data will be collected.
