If you live in a state that requires you to take a concealed carry permit course the instructor should have mentioned some local clubs and ranges that could offer some instruction, in fact if they feel that there is enough interest they may be willing to offer a course. Meanwhile I would look at joining a local range or club and talk to other members chances are that many of them also CC and can offer you some advice from their personal experiences. Locally I was friends with the local police chief and he actually encouraged me to get my permit after I moved up here. I would run into him several times a week and have a chat with him. Sadly now that he is the county sheriff I don't see him nearly as often, as his job keeps him rather busy.
I was lucky that I was good friends with many law enforcement people who offered me good advice and I often shot with them. The best advice they all gave me was not to carry unless I had made the mental commitment to be able to shoot without hesitation, if the need ever arose! Then practice, practice, practice!!!! The situations where a person would be justified to shoot are so varied so just set up some "What If" scenerios and repeat them until you can draw and fire without hesitation when the scenerio demands it.
