Kodiac, Go to the
www.idpa.com website and download the rule book. It will answer all your questions about equipment,courses of fire and there is just a bunch of good info there. It will make your first visit to a match more fun if you are a little familiar with what is going on.
Also you can go to this web site and watch a video and pictures of one clubs match. It will give you a good idea of what you may see. Especially the video.
