Welcome to GlockTalk! The best advice that I can give you is to shoot as wide a variety of hanguns as is possible for you to and go shooting as often as you can afford (time and money). Make friends on this forum and at the range and you'll get to shoot many different pistols.
Don't be afraid to get some professional or at least competent instruction. Sometimes new shooters learn bad habits from friends or family members and just keep practicing those bad habits. If you develop good habits in the beginning, you ll have a great foundation to build on in the future.
What part of SC are you in?
