None of the 3 guns I bought/traded for in the last week had to be called in. The benefits of having a CWP in Wyoming. Just fill out the 4473, show your CWP, and sign it, no check/call required. They just file it.
But even before that I had never been delayed, or had had any issues purchasing multiple firearms in a short period of time.
The dealer must report it even if they don't have to do a nics call.
(F5) As a licensed dealer, must I advise ATF if I sell more than one handgun to an individual? [Back]
If you sell or dispose of more than one handgun to any non-licensee during a period of 5 consecutive business days, the sale must be reported on ATF Form 3310.4, Report of Multiple Sale or Other Disposition of Pistols and Revolvers, not later than the close of the business day on which you sold or disposed of the second handgun. The licensee must forward a copy of the Form 3310.4 to the ATF office specified thereon, and another copy must be forwarded to the State police or local law enforcement agency where the sale occurred. A copy of the Form 3310.4 also must be attached to the firearms transaction record, ATF Form 4473, documenting the sale or disposition of the second handgun.
A business day for purposes of reporting multiple sales of pistols or revolvers is a day that a licensee conducts business pursuant to the license, regardless of whether State offices are open. The application of the term “business day” is, therefore, distinguishable from the term “business day” as used in the NICS context. Example: A licensee conducts business only on Saturdays and Sundays, days on which State offices are not open. The licensee sells a pistol to an unlicensed person on a Saturday. If that same unlicensed person acquires another handgun the next day (Sunday), the following Saturday or Sunday, or the Saturday after the reporting requirement would be triggered, the subsequent acquisition of a handgun would have to be reported on a Form 3310.4 by the close of the day upon which the second or subsequent handgun was sold.

To my knowledge thats the only real "flagging", the stuff people talk about related to nics calls seems like tin foil hat stuff.
Do you mean NCIC(National Crime Information Center - FBI database, Washington DC)
