The scope of this appears limited to home possession...will this change the status quo on concealed carry?
Not that I see - but, NYC can no longer not issue permits for ownership, eg, unless they have an individual reason.
In Chicago and New York, the restrictions on home possession mean that there is no CCW constituency.
If this results in Illinois and New York restrictions on ownership in the home, with the result that many people become gun owners, then there will be a constituency to agitate for "shall issue" CCW
