John Kielbasa, owner of Fernwood Firearms in Hankins, NY, acknowledged that "there was a small [gun sales] spike after the shooting," which he attributes to customers who are "worried about gun control."
They're also fueled by a desire to protect themselves, he said, noting that some of his customers are women. And while Kielbasa specializes in military-style tactical rifles, he said that all types of guns are selling.
The Connecticut State Police have identified the primary weapon in the attack that killed 20 children and six educators at a Newtown school on Friday as a Bushmaster AR-15 semiautomatic rifle with high capacity magazines. Police said that the shooter also used two semiautomatic pistols -- a Glock and a Sig Sauer -- before committing suicide.
A prior assault weapon ban, which expired in 2004, didn't eliminate the weapons entirely, but restricted their features, limiting magazine capacity to 10 rounds and regulating pistol grips, bayonet attachments and flash suppressors.
"There's been a significant shift to these types of rifles ever since the 2004 ban was lifted," Dionisio said.
Obama has indicated that he will try to bring back restrictions on military-style rifles. In the second presidential debate in the fall, Obama said he was going to see "if we can get an assault weapons ban reintroduced."
On Sunday, Obama, signaled the possibility of more action. "In the coming weeks, I will use whatever power this office holds to engage my fellow citizens ... in an effort aimed at preventing more tragedies like this," said Obama, in a speech at Newtown.
Democratic lawmakers also said they would introduce tougher legislation.
