(11,996 posts)1994 AWB limited new manufactured mags to 10 rnds.
Existing mags were exempt.
NY has passed a similar law to what you propose after sandy hook - 10 round limit (7 round load limit was deemed unconstitutional), on new mags, with no real grandfathering, but w/registration of existing mags (same with expanded-defined assault weapons).
The attempt there is to limit new builds, but to also, through attrition, reduce the existing stock because registered items are not transferable. 1 generation they should be gone.
Problem is only like 5% of the people were estimated to comply. AN unpopular law with little support even from LE, though it is used to push more criminal charges when applicable.
The latest federal AW bill would also grandfather, and specs serial numbered mags with the date on them for distinction.
As other posters have explained, millions and millions exist (some military somewhere uses the same mags).
Your notions are very good - and could limit "impulse" attacks to an extent (although having 6 10 round mags is only slightly better then 3 30 round mags); limit semi-auto or all repeating arms with detachable mags, and limit the capacity of the mags.
How to implement it and enforce it is the devil in the details, IF it gets passed. Having it not struck down as unconstitutional would also be a challenge, but may hold up, as others have.
