Tulsa, OK- An estimated 35,000 people came out to Wanenmacher's Tulsa Arms Show to visit more than 4,000 gun booths.
Gun owners and exhibitors say there's a good reason why.
"Our president Obama is not a pro-gun person and neither is his cabinet," said Joe Wanenmacher, owner of the show. "I think a lot of people are worried about possible new gun laws."
That includes people like Mike Dawson, who traveled all the way from Mobile, AL for the gun show.
Like many other gun owners here, he's been coming to the Tulsa gun show for years and every time he worries it could be the last.
"I'm scared that we may not see any more gun shows," he said. "This is the last, biggest gun show in the world."
This fear is manifesting itself in higher sales for gun stores and more conceal-carry permits.
In February, the Oklahoma State Bureau of Investigation reported an 87 percent increase in the number of applications to carry concealed firearms, according to the Associated Press.
But, it's not just politics fueling concerns.
The bad economy and the potential for increased crime are other factors gun sellers say are also leading to higher gun sales.
Some of them worry mass shootings like the ones over the weekend in New York and Pittsburgh provide ammunition for gun control advocates.
"When you take the number of folks that own firearms and the number of incidents that have happened within the last few days, the statistical numbers are minuscule," said Jay Shachter, a gun seller.
An annual scorecard compiled by the Washington-based Brady Campaign to Prevent Gun Violence ranked Oklahoma tied for last among the 50 states when it comes to strong gun laws. Oklahoma scored its only two points in the survey for not forcing colleges to allow firearms on campuses.
But, a bill's been introduced to allow college faculty members and some students with concealed carry permits to bring weapons onto campus.
