I purchased a restricted new from a supporting dealer a month or so ago, and the transfer from cfc and cfo took a day... My latest purchase from the exchange forum is almost a week old, and still nothing... time for another call to the cfo...
I've had restricted firearms for over 25 years, so it doesn't really seem to matter whether your new to the game or not... the cfo is the speedbump on the highway to receiving your new firearm...
Anecdotal story time... The first pistol I purchased (Llama 9mm) had all the paperwork done in a couple hours... Went to the local police department with the receipt and my FAC...received my permit to convey from the gun store to the police station. The store didn't have a box, and cases weren't necessary for transport back then (neither were trigger locks...), so I carried my pistol and mags into the lobby of the station in a paper bag. Got called in to have the serial number verified, and was issued a permit to transport home... Done... All manually entered, and the people were great... In fact I still know them today... Now with the wonders of modern technology, computers that have unlocked the humane genome, billions of dollars spent, and I still wait for the transfer to be completed... sad...
