I've had my C&R going on 10 yrs and cannot recal having to send a figerprint card in. Might be policy now though. Don't forget to notify your chief LEO that you are applying for the FFL (usually the county Sheriff). I believe you send them a copy of your form?
I gotta tell you, it's the best $30 I ever spent. It's saved me tons of cash over the years.
There is also a sticky thread on the C&R process in the C&R forum section.
