Sandel's Pawn Shop in Youngstown changed the age limit from 18 to 21 when it comes to buying an assault-style rifle in their store.

The shop's Vice President, Brett Fine, said in the wake of mass shootings and after an 18-year-old Pittsburgh Institute of Aeronautics student bought a gun from him, he thinks it's the right thing to do whether congress signs it into law or not.

"Whether it does or doesn't, I know my store, we're not going to do it," Fine said, "We're going to be 21 and above."

He said that based on experience working in gun sales, if a person waits until they're 21, it offers a better opportunity for the background check to catch red flags that they may not see when an 18-year-old comes in.

"You would have the opportunity to find out you know, a little more about them," he said, "what they may have done in those three years of 18, 19, 20."

Not only could a person potentially commit crimes during those three years that would stop them from owning a gun in the first place, but people grow psychologically during that time too.

Dr. Deirdre Adduci, a psychologist in Cortland, said the brain reacts differently when you're 18.

"I think the biggest difference between an 18-year-old and a 21-year-old is impulsive control," Adduci said, "and in that time, we are learning to better manage our emotions, we are learning to manage our impulsive control and we are also learning to respond versus react."

The gun bill passed the House mostly along party lines with five republicans supporting the measure.

It faces long odds in the Senate.
