Pursuant to 27 C.F.R. 478.126a, a Federal Firearms Licensee (FFL), must complete a multiple handgun report, or ATF Form 3310.4 (Report of Sale or Other Disposition of Pistols and Revolvers), when the FFL transfers two or more handguns to the same person in a single transaction or within five (5) consecutive business days.
If you report a multiple sale to the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), and the same person comes back within five (5) days of that sale and acquires another handgun, another multiple handgun report must be filed. You should also check off the box that this form is a supplemental form, supplementing the original multiple handgun report.
So, as an FFL, how do you ensure that you do not fail to file a multiple handgun report?
While most FFL software programs include alerts for multiple handgun sales within a five day period, many FFls cannot afford the cost of such software. Therefore, I suggest that you should keep a separate handgun sales log that must be checked before each handgun sale. This will prevent failures to report to ATF.
