The OP is asking about whether he should carry at his college, where it is legal, once it becomes legal for him to do so.
When I was in GA years ago, what I carried was based on my dress level and location.
Cool weather/away from work: Glock 23
Warmer weather/away from work: Kel-Tec P11
At work (legal but prohibited by company policy): P32
The really important thing is to get good with what you carry. When I practiced regularly with it, I could hit a 2-liter bottle with the P11 at 25 meters. Hopefully you'll never have to shoot that well in an emergency, but you should be capable of rapidly drawing whatever you carry, and putting at least 2 rounds, with no misses, into a target 10 meters away.
