Two tables sit side by side at the same show. At one, you fill out a federal form and wait on a background check. At the other, money changes hands and you walk away. Both can be perfectly legal — or the second one can be a serious crime — depending entirely on where the show is and who's involved. Here's how the two paths differ and how to know which rules apply to you.
The two kinds of tables
A licensed dealer — a Federal Firearms Licensee, or FFL — must follow the same federal process at a gun show as in a storefront: the buyer completes ATF Form 4473, the dealer runs a NICS background check (or verifies a qualifying state permit where applicable), and the transfer is logged in the dealer's records. That's true in all fifty states, at every show, no exceptions.
A private seller — an individual selling from a personal collection who is not engaged in the business of dealing firearms — is not required by federal law to run a background check or keep transfer records when selling to a resident of the same state. This is the arrangement often loosely called the "gun show loophole," though it isn't specific to gun shows and applies to private sales generally under federal law.
Why "federal law" isn't the whole answer
Roughly twenty states plus the District of Columbia layer their own requirements on top of the federal baseline, and those state rules are what actually determine whether a private table sale is lawful. The state approaches generally fall into a few categories:
| Approach | How it works in general terms |
|---|---|
| Universal background checks | All or most transfers, including private sales, must go through a licensed dealer or a designated check process |
| Permit-to-purchase | Buyers must hold a state-issued purchase permit or license, which itself requires a background check |
| Handgun-only rules | Private long-gun sales are treated differently from private handgun sales |
| Federal baseline only | No state-added requirement; the federal private-sale rules described above apply |
Which category your state falls into changes with legislation and litigation — several states have moved between categories in recent years — which is exactly why this article describes the categories rather than publishing a list that could be wrong by the time you read it.
The 2026 wrinkle
In June 2026, a federal district court in Texas vacated the ATF's 2024 rule that had expanded the definition of being "engaged in the business" of dealing firearms — the definition that determines who must hold an FFL and run background checks. Replacement rulemaking is pending. The practical takeaway for show-goers: the boundary between "private collector selling a few guns" and "unlicensed dealer who needs an FFL" is governed by the older statutory standard while this plays out, and that boundary was never a bright line to begin with. Sellers moving significant volume for profit have always risked crossing it regardless of which rule is in force.
Crossing state lines
One rule that trips up show visitors constantly: federal law generally prohibits a private sale of a handgun to a resident of another state — interstate handgun transfers must go through an FFL in the buyer's home state. Long guns have somewhat more flexibility under federal law when a dealer is involved, but private interstate sales remain heavily restricted. If you're attending a show across a state border, assume any purchase you make will need to route through a dealer unless you've verified otherwise.
How to verify your state's current rules
- Check your state attorney general's or state police website — most publish current firearm transfer requirements in plain language.
- Ask an FFL at the show. Dealers work under these rules daily and most will give you a straight answer, especially since the safe harbor for any ambiguous situation is simply running the transfer through their table.
- When in doubt, use a dealer transfer. The fee is modest, the paperwork takes minutes, and it converts every open legal question into a documented, checked transaction.
The bottom line
Both kinds of tables have a legitimate place at most American gun shows, but the private-sale rules are a patchwork that changes by state and by year. Know your category before you go, and when the situation is unclear, the FFL table is always the answer that lets you sleep at night.
