I agree that we may be a ways of from being able to buy a mine at Tractor Supply or a MANPADS at Walmart. But there may be some items that perhaps the restrictions for which could be relaxed. Maybe try silencers for .22s first. If there isn't a huge increase in crimes involving suppressed .22 pistols and rifles, then maybe move to center fire versions.
I never talked to anyone who had to fire their gun who said "I wished I had the smaller gun and fewer rounds with me" Just because you find a hundred people who agree with you on the internet does not mean you're right.
