I don't think ATF ever did that. However, Connecticut allows a private citizen to transfer out of one's possession a maximum of 10 handguns per year before being considered a dealer, with all the licensing requirements thereof. Handguns are registered here, and sales/transfers must be approved, CCW to CCW, or CCW to dealer, [also dealer to CCW], by the CT State Firearms division.
The ONLY way to purchase/transfer a handgun in CT is with a concealed carry pistol and revolver permit. That is the only handgun permit offered.
Long guns, so far, are not registered, and so, don't apply here.
