Automatically detects when the same buyer purchases two or more handguns within 5 business days — so you never miss the 24-hour ATF reporting window.
Get Started →Federal law requires FFLs to file ATF Form 3310.4 whenever the same person purchases two or more handguns within five consecutive business days. Missing that filing window isn't a technicality — it's a federal reporting violation. 4473 Pro's 3310.4 Tracker automatically identifies these transactions as they appear in your audit data, so the filing requirement never catches you off guard.
Under 18 U.S.C. § 923(g)(3), federally licensed dealers must report to ATF — and to local law enforcement — whenever a buyer acquires two or more pistols or revolvers, or any combination of pistols and revolvers, within five consecutive business days. The report must be filed within 24 hours of the triggering sale using ATF Form 3310.4 (Report of Multiple Sale or Other Disposition of Pistols and Revolvers).
The requirement applies to handguns only — rifles and shotguns are not reportable under 3310.4. Long gun transfers to the same buyer within any timeframe do not trigger the filing requirement.
When you audit a batch of forms, the AI extracts the transferee name, firearm type, and transfer date from each form. The 3310.4 Tracker then checks your complete audit history for any instance where the same buyer appears with two or more handgun transfers within a five-business-day window.
Flagged buyers appear in your audit results with a clear alert showing which transfers triggered the flag, the dates involved, and a reminder that a 3310.4 filing is required. The flag is tied to your audit data — it updates automatically as new forms are audited.
In a busy retail FFL, it's easy to lose track of who bought what and when. A buyer who purchased a Glock on Thursday afternoon and comes back the following Tuesday for a Sig — that's two handguns in five business days. If you're not actively cross-referencing your transfer log against prior sales, that filing requirement can slip through entirely.
The consequences of missing a 3310.4 are real. ATF inspectors specifically look for multiple handgun purchases in bound book records and cross-reference them against filed 3310.4 reports. A pattern of unreported multiple sales is one of the more serious recordkeeping violations an inspector can find.
The 3310.4 Tracker identifies the obligation — you still need to complete and submit the actual ATF Form 3310.4. The form requires the buyer's personal information, identification details, and the firearm descriptions for both transfers. The completed form must be sent to your local ATF field office and to the local law enforcement agency where the sale occurred within 24 hours of the second transfer.
Keep a copy of every 3310.4 you file. ATF can request documentation of filed reports during an inspection.
The 3310.4 filing window is 24 hours. 4473 Pro flags the requirement automatically — before the clock runs out.
No. ATF Form 3310.4 applies to pistols and revolvers only. Long gun transfers — rifles, shotguns — do not trigger the federal multiple-sale reporting requirement under 3310.4, regardless of how many are sold to the same buyer.
The 3310.4 requirement applies per licensee. If a buyer purchases one handgun from your store and one from a different FFL, each FFL is only responsible for their own transactions. The tracker only sees forms you've audited through your account.
No — the tracker identifies the filing obligation and provides the relevant transaction data. You or your staff must complete and submit the actual ATF Form 3310.4 to your ATF field office and local law enforcement within 24 hours of the triggering transfer.
