ATF Form 3310.4: The Multiple Handgun Sales Report, Explained for FFLs

The trigger is two or more pistols or revolvers going to the same unlicensed buyer within five consecutive business days. That can be two handguns in a single transaction, or one handgun on Tuesday and a second the following Monday. The window counts business days for your store, so days you are closed do not count against the five.

• A buyer purchases two pistols in one sale: report required, filed the same day.
• A buyer purchases one revolver, then returns three business days later for a pistol: the second sale triggers the report, and both handguns go on it.
• A buyer purchases a pistol and a rifle together: no Form 3310.4, because only one handgun was transferred.
• A pawn customer redeems two of their own pawned pistols within the window: the ATF treats a pawn redemption as a disposition, so the report is required the same as a sale. Confirm any edge case with your ATF Industry Operations Inspector or counsel.

The report must be submitted by the close of business on the day the multiple sale occurs. You file it twice:

• To the ATF's National Tracing Center, by fax, by mail, or electronically through the ATF's online reporting options.
• To the chief law enforcement officer (CLEO) where the buyer resides, typically the sheriff or chief of police listed for the buyer's address.

Keep a copy of every filed report in your records. The ATF expects to see your 3310.4 copies during a compliance inspection and will compare them against your A&D Book and completed 4473s to confirm that every qualifying multiple sale was reported.

• Missing the second sale. The single-transaction case is easy to catch. The Tuesday-then-Monday case is where paper processes fail, because nobody at the counter remembers the earlier sale.
• Filing with the ATF but not the CLEO, or the reverse. Both copies are required.
• Filing late. The deadline is close of business on the day of the qualifying sale, not the end of the week.
• Counting calendar days instead of business days, which shortens the window and misses reportable pairs.

Unreported multiple sales are a recurring finding in ATF compliance inspections, and they are almost always process failures rather than intent. A counter that depends on staff memory will eventually miss one during a Saturday rush.

Because e4473 is built into the Bravo Store Systems point of sale, every handgun transfer is already tied to the buyer's record. The system can flag a second handgun sale to the same buyer inside the five-business-day window at the counter, before the transfer completes, so the report gets filed on time instead of surfacing as a violation two years later. Your completed 4473s, A&D Book entries, and multiple-sale flags live in one system, with one company accountable for all of it.
