Gun enthusiasts across the region made their way to the Dakota Territory Gun Collectors Show in Rapid City, breaking previous attendance records.
Organizers say the call for stricter gun regulation is increasing the demand for firearms and ammunition, causing the price to go up.
"A lot of that ammunition is three times what it used to be," said Dakota Territory Gun Show Manager, Sonny Pesicka. "And if you look at any of the stores in town here, you can't find any."
The issue of gun regulation has spurred debate for a number of years, but in the past few months it has dominated the conversation in Washington.
Across the hall from the gun show at a public hearing, locals who support of the 2nd Amendment had a chance to send a message to lawmakers via transcript.
"It's the best thing that a citizen can do to defend themselves," said gun rights activist Ed Assman. "And I also believe that our forefathers intended it to be one of the guarantees, to have a continually free America."
Newly proposed gun laws, including assault weapons ban, high capacity magazine ban, and expanded and universal background checks. The hot topic has people on both sides of the issue deeply concerned.
"You and I both know there are people who shouldn't have guns and I know people that shouldn't have guns," said Pesicka. "The background check that's a good idea."
If congress tightens the grip on guns, proponents for ownership say the type of illegal weapons could become a blur, which is something gun rights supporters are working to prevent.
"A right is called a right for a reason," said Civil Rights Lawyer, David Frankel. "It's not negotiable."
The U.S. Senate did agree Thursday to move forward with a debate on gun legislation that could lead to the most significant change in nearly 20 years on the federal level.
A bipartisan 68-31 vote rebuffed an effort to keep debate from starting.
