American gun enthusiasts can express their zeal on an upcoming "Gun Appreciation Day" right before Barack Obama is sworn in for a second term as president.

A new coalition of gun rights and conservative groups is urging Americans to show support for the right to carry firearms by turning out in large numbers on Jan. 19 at gun stores and firing ranges.

"The Obama administration has shown that it is more than willing to trample the Constitution to impose its dictates upon the American people," said Gun Appreciation Day Chairman Larry Ward.

In the wake of the shooting last month in Connecticut, which claimed the lives of 20 children and six elementary school workers, Obama said he will support a new bill to restore a ban on military-style assault weapons.

"We need to ban politicians who assault our rights, not firearms that are used thousands of times a day to protect lives and property from criminal attack," Second Amendment Foundation founder Alan Gottlieb said.
