• McCain praised the June 2008 Supreme Court decision striking down
the District of Columbia's gun ban. “Obviously I am very pleased
about that decision,” he said. “We had filed an amicus brief with 54
other senators. So I am pleased with that ruling." 

• He opposes holding gun manufacturers liable for crimes using a
firearm and has voted to protect gun manufacturers from such
liability. He has however supported legislation requiring gun
manufacturers to include gun safety devices such as trigger locks in
product packaging.

• McCain supports assault weapons and concealed weapons and has voted
consistently against such bans or restrictions.  Most recently he
opposed an amendment to extend a ban on 19 specific firearms, and
others with similar characteristics.

• He believes that banning ammunition is just another way to
undermine Second Amendment rights. He voted against an amendment that
would have banned ammunition marketed or labeled as ‘armor-piercing.’

• McCain introduced legislation that would require an instant
criminal background check for all sales at gun shows. He supports
instant criminal background checks for gun buyers and wants them to
be conducted thoroughly, efficiently, and without infringing on the
rights of law abiding citizens or effectively blocking transactions.

• McCain supports the importation of certain types of high capacity
ammunition magazines and has voted against any limitations. 

• McCain believes in strict, mandatory penalties for criminals who
use a firearm in the commission of a crime or illegally possess a
firearm. Enforcing the current laws on the books is the best way to
deter crime.

• Obama addressed the June 2008 Supreme Court decision striking down
the District of Columbia's gun ban by saying, “I have always believed
that the Second Amendment protects the right of individuals to bear
arms, but I also identify with the need for crime-ravaged communities
to save their children from the violence that plagues our streets
through common-sense, effective safety measures. The Supreme Court
has now endorsed that view, and while it ruled that the D.C. gun ban
went too far, Justice Scalia himself acknowledged that this right is
not absolute and subject to reasonable regulations enacted by local
communities to keep their streets safe.”

• Obama has a history of supporting gun control. 

• Obama supports a ban on assault weapons and concealed weapons.

• He would crackdown on unscrupulous gun dealers.

• He voted against prohibiting lawsuits against gun manufacturers.
