I would highly suggest you:
Find some friends that are experienced with handguns, ask them to take you to a range and explain the weapon and 5 safety rules. Then have them let you try their handgun, if they feel comfortable doing so.
and/OR
Find any of the local ranges that rent guns, call them, and tell them you are a new to firearms, just completed the CCDW course and looking for your first gun, what they have to rent, as well as specific courses for you to take.. and then take them.
