Sucks to be in states that require their own check on top of the federal. Bummer. I like Idaho, even though there isn't the reciprocity that some other states' permits allow. Personally, I obtained the CWL to carry concealed, especially back when I was commuting 330 miles a day, and then later, when I clerked in a pawn/gun shop. Been right handy at least a half dozen times. Bypassing the federal NICS is a bonus.
There are several things that folks should know about using the CWL to bypass. As I'm sure everyone knows, federal law allows persons to purchase long guns across state lines, as long as the purchase is legal in the purchaser's home state and the purchase is done face to face. Not so with handguns, they must go from the store, to an FFL in the purchaser's home state, where it still must pass legal muster.
Second, to use a CWL to bypass NICS, the purchase MUST be made in the state where the CWL was issued, long guns or handguns, no argument.
When the NICS is called in, the call does NOT go to BATFE, nor to the FBI! The call goes to a contractor that is contracted with by the FBI, who's records have great huge holes in reporting the records of felons to the data base.
If the purchase is made in a state where the call goes to a state agency, that agency calls the same federal contractor that all other FFL's call, and while that's happening, they're checking the state's records as well.
If you believe that if you use a CWL to bypass the NICS, and that's the end of it, you had better know that if that FFL where the purchase was made is subjected to a records check by BATFE, those 4473's that indicate a NICS bypass are flagged, and at some point, those names and identities ARE eventually checked.
If your name continually brings a postponement or denial, it's most likely that a felon or other "person of interest" with the same or SIMILAR name is tripping the denial. If you look on the 4473, you'll see a block where a person can use a "unique personal identifier". That alpha-numeric identifier is obtained by filling out a federal form, sending it in, and then the FBI issues that identifier that you must keep and remember for all subsequent purchases. When the FFL calls it in, they give that identifier to the contractor, and it goes straight to the detailed background check that t he FBI did before issuing it, and will give you a "go". Gotta know, though, that your personal information becomes a part of FBI's permanent record, and includes a lot more information that just not having a felony, or other disqualifier!
Hope that helps clear some things up, but it's been awhile, and maybe with THIS current regime, things have changed, especially in light of the DoJ now requiring southwestern states to report ALL purchases of semi auto firearms that hold more than five rounds......
