"It shocked me pretty big, it hit me pretty hard I'll tell you that," one student said.
In the Breedlove Building, a classmate noticed a 9mm handgun on student Brett Ward's hip and told campus police.
It was before a noon class in room 207 when his teacher took him out into the hall and police confronted him.
He had the Glock in his vest pocket and without incident, handed it over to police and was taken into custody.
"Number one, he violated the law in that he carried it on campus. Number two, that he doesn't have a carry license," UAFS Chancellor Paul Beran said.
The 23-year-old told police he was in the Army National Guard and recent school shootings had him concerned about his safety on campus.
"The student was concerned based on the things that have happened recently at institutions and had a misguided sense of reality that carrying one on our campus was going to make him safer," Beran said.
Something some students agree with.
"By all means, you have a right to protect yourself. If he had no means to shoot someone on campus that wasn't gonna hurt him, then I don't see the big issue," one student said.
But not everyone.
"It was after the fact when I found out but now that I think about it, pretty nervous you know, cause anybody could just bring a gun on campus, you know it was that easy for him to bring it," another student said.
But Beran assures students that safety remains a top priority.
"I personally know that we do not have a significant threat on this campus and the students are in a very safe environment here," he said.
Ward will not be allowed back on campus without following disciplinary procedure. Campus officials do not yet know if they will allow him to return to UAFS in the future.
