You do not say where you are from or which state you go to college... that may affect what you buy if new!
Here is a list from California and it goes from this to not being able to buy until you are 21.

So with that out of the way my first three handguns were revolvers in the .22 and .357 range, however the choice on all aspects of the handgun is best found with renting at a local range (which has been noted already).
Under federal law I don't think you can buy a handgun from a dealer under 21... there are some exceptions for private party transfers. States have their own requirements. I'm not sure you can even rent a handgun until you turn 21.
So, we can give you basic advise but other than point you to rent and see how you like different caliber and handgun types I will not give specific recommendations.
