A firearm comes up missing. Maybe a physical count does not match the bound book. Maybe a customer's gun walks off the bench. Maybe the morning crew finds an empty hook that was full at close. Whatever the trigger, you now have two clocks running: the 48-hour federal reporting clock, and the much longer clock the ATF and your carrier will use to judge how you ran the shop before this happened.
The report itself is not the hard part. The hard part is knowing fast enough that you have something to report.
What the rule actually requires
Federal law requires an FFL to report the theft or loss of a firearm from inventory to the ATF, and to the appropriate local law enforcement agency, within 48 hours of discovery. The federal reporting requirement sits at 18 U.S.C. § 923(g)(6), and the ATF form for it is Form 3310.11, Federal Firearms Licensee Theft/Loss Report.
A few things worth being precise about:
- The 48 hours runs from discovery, not from when the firearm actually went missing. Those are often different days, sometimes different months. That gap is exactly why your inventory discipline matters.
- A theft and a loss are both reportable. "Loss" covers the gun you cannot account for and cannot prove was stolen. You do not get to wait until you decide which one it was.
- The report goes to both the ATF and local law enforcement. One does not substitute for the other.
- This applies to firearms in your inventory. Confirm the current treatment of customer-owned firearms and any other edge cases against the current form instructions, because the details matter and they are not all intuitive.
This is not legal advice. Pull the current Form 3310.11 and its instructions before you file, and bring in counsel if the circumstances are serious.
Discovery is the whole game
The 48-hour clock is generous if you find the problem the day it happens. It is brutal if you find it during an annual count and realize the last clean inventory was eleven months ago. Now you are explaining to an IOI how a firearm sat unaccounted for that long, and the theft/loss report is the smallest of your problems.
This is where the bound book stops being paperwork and starts being your alibi. A clean, current acquisition and disposition record is what lets you say, with confidence, exactly what you have and exactly what is missing. A sloppy one means you cannot even prove a gun is gone, let alone when it left.
Remember the disposition-timing rule that drives so many findings: a disposition is recorded not later than seven days following the date of the transaction, under 27 CFR § 478.125(e). An open disposition is not a theft, but a pile of open dispositions is how a shop loses track of what is real inventory and what is already out the door. When your book is behind, every reconciliation becomes a guessing game, and guessing games do not beat a 48-hour clock.
The pattern an inspector reads
A single theft or loss report, filed on time, with a tight bound book behind it, reads as a shop that knows its inventory and follows the rule. That is the story you want.
The other story is the one that escalates. Late discovery. A reporting date that does not square with the records. Multiple firearms unaccounted for with no clear loss event. Inventory shrinkage that nobody caught because nobody was counting. DealerReady's review of FFL claims shows the large majority of trouble traces back to documented counter and recordkeeping errors, not dramatic events. A missing gun is dramatic. The recordkeeping failure that let it stay hidden is the ordinary, trainable kind.
That is the part you control: build the habits that surface a discrepancy fast, so the 48-hour clock starts when you can still beat it.
What trainable looks like here
The staff-meeting version of this, "if something goes missing, tell me," does not survive turnover and does not survive a busy Saturday. The trainable version is concrete:
- Regular physical counts reconciled against the bound book, on a cadence the shop actually keeps, so a discrepancy surfaces in days, not months.
- A clear discovery-to-report procedure every staffer knows: who gets told, who files Form 3310.11, who calls local law enforcement, and the 48-hour deadline that governs all of it.
- A bound book kept current so the count means something. Acquisition and disposition requirements run through 27 CFR § § 478.121 through 478.129, and electronic recordkeeping is permitted under ATF Ruling 2008–2. Whichever system you run, it only protects you if it is current.
- Documentation that the training happened. "We covered it" is not a defense. A dated certificate is.
Our Bound Book Management course covers the acquisition and disposition fields, the disposition-timing rule, electronic systems, and the reconciliation discipline that turns a missing-gun problem into a same-day discovery instead of a year-end disaster. For the broader picture of what an IOI looks for and how findings escalate, the ATF Inspection Defense course puts the theft/loss obligation in context with the rest of the inspection.
The carrier angle
Theft and loss are exactly the kind of exposure an FFL carrier cares about, and exactly the kind they will ask about at renewal. Documented inventory training and a clean reporting procedure are evidence that you manage that risk, not just react to it. DealerReady gives you dated, verifiable certificates a carrier can confirm by certificate ID, formatted for carrier submission. It is not a guaranteed discount, and it is not ATF accreditation, because the ATF does not accredit private training. It is the documentation a carrier will accept and may credit.
If the answer for your shop is "get everyone counting the same way and prove it," that is a shop plan and the admin dashboard behind it. See shop plans and pricing to roll it out across the team. Find the firearm before the inspector does, file inside the 48 hours, and keep the paper that shows you ran the shop right.
