The standard class is a four to six hour classroom course with a multiple-choice test, followed by a hands on practical exam. You will be given a certificate of completion that is necessary to turn in to the state to get your license to carry permit.
The new to handguns class covers everything the standard class does, but places more emphasis on fundamentals. Also, handgun experience and personal coaching is offered before the practical exam.
