Fort Worth's Mark Greene, a hunter and former member of Gun Owners for Obama, said he's tired of people using this argument to influence Obama's re-election bid.
"I still own guns and I still support Obama," he said. "And I still have very little in common with the fear mongers and bunker-mentality gun nuts who will tell any lie they think they can get away with to try and bring down this president they hate so vehemently and irrationally."
Some in the industry cite a variety of reasons for the rise in gun and ammo sales, including that manufacturers are better marketing guns -- primarily pink ones -- to women.
But a big reason may be politics.
A prominent businessman recently shopped at Cheaper Than Dirt, saying that "Republicans don't have a prayer against Obama" this year. That man, Irwin said, spent $25,000 on ammunition, magazines and other gun paraphernalia.
"The folks paying attention to the political climate think this might be an opportunity to stock up," Irwin said.
John Woods, who has lobbied for legislation to keep guns off college campuses, said many fears surfacing are unwarranted.
"The gun lobby has long known that fear is a remarkable marketing and fundraising tool," said Woods, a graduate student at the University of Texas at Austin who attended Virginia Tech and lost his girlfriend in the 2007 shooting there that claimed 33 lives. "But the Supreme Court ruled recently that the Second Amendment is an individual right, so that fear is completely misplaced."
Not everyone is stocking up.
Robert Chafin, who lives in Denton County, says he was among those who stocked up during Clinton's presidency.
"I stockpiled a variety of firearms that I feared might not be available in the future," he said. "As it turned out, in the wake of the disaster that befell the Democratic Party in the '94 elections, attacks on firearms ownership evaporated as Democrats learned a painful lesson. And it appears they have remembered that lesson."
That's why he isn't stockpiling right now, he said, even though Obama's "administration has waged an oblique war on gun owners."
He and others point to the Operation Fast and Furious gun-smuggling investigation.
Officials say it was intended to track down and break up groups of people running guns to Mexican drug cartels.
But Chafin says the effort was simply "trying to build a case for banning private sales."
"I'm sure that Barack Obama himself would institute a total ban on gun ownership if he could," Chafin said. "[But] he would never be able to put together any sort of consensus in Congress for additional restrictions on private firearms ownership."
He also pointed to several high-profile court rulings -- from invalidating the handgun ban in Washington, D.C., to quashing the handgun ban in Chicago -- that he believes will protect gun rights regardless of who is in the White House.
As Obama seeks a second term, groups such as Ammo.net are calling the president "the greatest gun salesman in America."
"American firearm sales and concealed handgun permit applications are at all-time highs since the 2008 election of President Obama," according to a graphic on Ammo.net. "The increase in Americans purchasing firearms has meant massive increases in sales by gun makers, billions more in federal and state collections related to firearms and ammunition, and hundreds of thousands of new Americans carrying concealed handguns.
"Given these increases, should the firearms industry support President Obama for a second term or not?"
January was the 20th straight month of increases in firearm background checks. States such as Utah saw a 161 percent increase in the number of concealed-weapon permits from March 2008 to March 2011. And Glock sales in the U.S. grew 71 percent in the first quarter of fiscal 2010, according to the ad.
In Texas, the number of concealed-handgun permits has gone up every year, nearly doubling since 2006.
"I think the president being called 'the greatest gun salesman in America' has more to do with him being a Democrat than anything else," Woods said.
