A guy buys a handgun on Tuesday. He comes back Saturday, looks at a second one in the same caliber, and buys it. Same buyer, two pistols, four days apart, from your shop. You just triggered a multiple-sale report, and the clock is already running.
This is one of the most predictable findings an IOI can write up, because it does not depend on a judgment call at the counter. The transactions are in your bound book and on your 4473s. Either the report went in on time or it did not. There is no "we meant to." That makes it both easy to miss on a busy week and easy to train against.
When the report is owed
The trigger is narrow and specific. You owe a multiple-sale report when you sell or otherwise dispose of two or more handguns to the same unlicensed person at one time or during any five consecutive business days. Pistols and revolvers count. Long guns do not, outside the special border-state reporting that some dealers in the Southwest are subject to.
A few things people get wrong:
- It is two or more, not three. Two handguns inside the window is the trigger.
- "At one time or during five consecutive business days" means a single transaction counts, and so do two separate transactions a few days apart. The buyer does not have to walk out with both at once.
- Business days, not calendar days. Tuesday to Saturday with your shop closed Sunday and Monday is a different count than five straight calendar days. Know your own schedule.
- Same buyer. The report follows the transferee, not the firearm.
The report is ATF Form 3310.4. It goes to ATF and, by statute, to the state or local law enforcement agency where the sale took place. The federal piece is the part dealers most often fumble.
The deadline is the finding
The report is due by the close of business on the day the multiple sale occurs, meaning the day the second handgun is transferred and completes the trigger. Not the day you noticed. Not the following Monday when the manager is back. The day it happens.
That is why this finding tracks so closely with who is working the counter. The first sale was clean. The second sale was clean. The failure is the report that did not go in because the person running the Saturday transaction did not connect it to the Tuesday transaction, or did not know the window existed. A new hire three weeks in is exactly the person standing there when the repeat buyer comes back.
How to file it clean
The mechanics are not hard once someone has actually been walked through them. The discipline is.
- Catch the trigger at the point of sale. Before you complete the second transfer, your process should surface that this buyer bought a handgun from you inside the window. That is a bound-book habit and a 4473 habit, not a memory test.
- Pull the data straight from your records. The 3310.4 wants the buyer's identifying information and the firearms' make, model, serial number, and type. Take it from the 4473s and the bound book so the report matches your records exactly. Mismatches between the report and the book are their own avoidable problem.
- File the day of the sale. Send the federal copy to ATF and the required copy to the appropriate state or local agency by close of business.
- Keep your copy. Retain it with your records. Your required records run for 20 years under 27 CFR § 478.129, and the multiple-sale report is part of the paper trail that shows a clean transaction during an inspection.
Confirm the current Form 3310.4, its instructions, and where your state copy goes against current ATF sources. States differ on the recipient agency, and the form gets revised.
Why this is a training problem, not a paperwork problem
The multiple-sale report fails for the same reason the skipped Section A question fails: the person at the counter did not have the rule in front of them when it mattered. DealerReady's review of FFL claims points the same direction. The large majority trace back to documented counter and recordkeeping errors, not to anything exotic. Predictable findings are trainable findings.
The lever is making the trigger second nature for everyone who runs a transaction, not just the compliance lead. That is what role-based training is for. Multiple-sale reporting is part of the counter workflow our 4473 completion and recordkeeping course covers, and it sits naturally inside Counter Certified, the credential for the people actually running sales. When a repeat handgun buyer walks back in on a Saturday, you want the staffer to recognize it without thinking, file the report by close of business, and have a dated certificate on file proving they were trained to do exactly that.
That last part matters at renewal too. "We covered it at a staff meeting" is not something a carrier can audit. A dated certificate with a verifiable ID is. Our shop plans put that documentation in an admin dashboard and format it for carrier submission, so the same training that prevents the finding also stands up when your carrier asks how you manage counter risk.
None of this is legal advice, and it is not a substitute for the current ATF form and instructions. It is the baseline and the paper trail. Get the trigger right, file the day it happens, and keep your copy.
