When was the last time a gun ban/law expired? And what was it?
Never in history, as far as I know.
When it was enacted in 1994--they put the "sunset" clause in to get some RINOs and Conservative Democrats to bite off. It was almost killed in Conference 3 times.
It turned out to be a disaster for the Democrats in the next election, including the first time a sitting Speaker of the House had been defeated.
