Here's what I think I know:
-No handguns unless your pistol registration is 1983 or older
-long guns okay(?)
If someone can tell me if I'm wrong, or add any additions that I know, it's greatly appreciated.
Everything you mention seems correct.
I don't have the time to run through the shitstorm that is Chicago's gun law ordinances, but here's the link which should answer all your questions:
Edit: Fixed link to a direct one. Those on dial-up, be advised it goes to a big PDF.
Only criminals are allowed to carry
Only criminals are allowed to have handguns and such
We (the law abiding citizens) can have long guns and baseball bats, and some knives if they are less than 4" in blade length.
Correct on the handgun registration, 1983. No way around it, period.
Fudd long guns can be registered in the city limits. IIRC, there's actually places on the extreme southside where you can hunt birds in the Chicago city limits, believe it or not.
Correct on EBR's for the most part, as Cook County has it's own AWB that bans most EBR's by name (or variants thereof).
I am still waiting to see the "features" ban that's supposed to exist for Chicago proper.
If the Chicago "features ban" turns out to be a myth, there would be a definite, definite loophole to register a non-Colt AR15 in the Chicago city limits- presuming you were willing to fight it when the Chief laughed at you and said he wouldn't accept the registration even though it's perfectly legal and he is obliged to do it.

Assholes in positions of high authority in that city act like gods to a degree not seen since ancient Rome, in spite of the fact that amongst them, an IQ over 110 is about as common as a Chicago handgun registration.
