Arkansas implemented an Enhanced CHCL and it has some different qualifying requirements and an extra 8 hours of class room time. It lets you carry in state buildings, on college campuses (no sporting events), in bars, and other "sensitive" locations. A holder can even carry in airports right up to the TSA check point...
And I agree! During the course we waited for the folks qualifying for basic CHCLs and it was terrifying!!! The plus side was our instructor brought his supressed B&T 9mm rifle. It had the Franklin trigger that fires once when you pull it and once when you release it! Super fun to shoot once you got a good rhythm down!
