I totally forgot about this thread until I was doing some research today on the current banned semi's in Cook county for a buddy and discovered why they are banned in every range around here. They aren't even sold here in Illinois or I haven't seen one in a case at any of the gun shops I frequent. IL has a melting point law and Hipoint doesn't meet the requirements.
(720 ILCS 5/24-3) (from Ch. 38, par. 24-3)
Sec. 24-3. Unlawful sale or delivery of firearms.
(A) A person commits the offense of unlawful sale or delivery of firearms when he or she knowingly does any of the following:
(h) While holding any license as a dealer, importer,
manufacturer or pawnbroker under the federal Gun Control
Act of 1968, manufactures, sells or delivers to any
unlicensed person a handgun having a barrel, slide, frame
or receiver which is a die casting of zinc alloy or any
other nonhomogeneous metal which will melt or deform at a
temperature of less than 800 degrees Fahrenheit. For
purposes of this paragraph, (1) “firearm” is defined as in
the Firearm Owners Identification Card Act; and (2)
“handgun” is defined as a firearm designed to be held and
fired by the use of a single hand, and includes a
combination of parts from which such a firearm can be
assembled.
For some reason I can't find why polymer firearms aren't in this. Because polymers certainly have a melting point lower than 800f. But that is the reason they aren't allowed in the ranges around here. It was also known as the "Saturday night special" law.
