-Requires owners of existing "assault weapons" to register them with the federal government under the National Firearms Act (NFA). The NFA imposes a $200 transfer tax per firearm, and requires an owner to submit photographs and fingerprints to the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE), to inform the BATFE of the address where the firearm will be kept, and to obtain the BATFE's permission to transport the firearm across state lines.
-Prohibits the transfer of "assault weapons." Owners of other firearms, including those covered by the NFA, are permitted to sell them or pass them to heirs. However, under Feinstein's new bill, "assault weapons" would remain with their current owners until their deaths, at which point they would be forfeited to the government.
-Targets handguns in defiance of the Supreme Court. The Court ruled in District of Columbia v. Heller that the Second Amendment protects the right to have handguns for self-defense, in large part on the basis of the fact handguns are the type of firearm "overwhelmingly chosen by American society for that lawful purpose." Semi-automatic pistols, which are the most popular handguns today, are designed to use detachable magazines, and the magazines "overwhelmingly chosen" by Americans for self-defense are those that hold more than 10 rounds. Additionally, Feinstein's list of nearly 1,000 firearms exempted by name (see next paragraph) contains not a single handgun.
Sen. Feinstein advocated banning handguns before being elected to the Senate, though she carried a handgun for her own personal protection.
