This isn't just "proposed", this is now LAW in Cook County. Moving this legislation up to the entire State is almost a formality at this point.
You guys are SCREWED.
I live in suburban Cook County. You may be mistaking the City of Chicago (which bans gun ownership)from other towns (most of whom do not).
Illinois requires a Firearm Owner ID card to handle or purchase guns. So far, it is not an onerous process to get one, although the anti-gun crowd seems to have really driven up the prices of hand guns.
The proposed legislation on supposed "assault rifles" sounds like it affects hunters and serious collectors. (I am neither, but I support their cause).
My guess is that gun shops will be happy with this. I purchased my first handgun in 2000 when I feared that Algore would be elected. The salesman said business was particularly booming that year.
