Buying your first gun in the United States comes down to a short sequence: confirm you’re legally eligible, choose a licensed dealer, fill out a federal transaction form, pass a background check, and wait out any state-mandated delay before taking the firearm home. At the counter, the paperwork itself is usually quick. The parts that trip people up are eligibility, state permit rules that vary widely, and the responsibilities that attach the moment the gun leaves the store with you.
Are You Eligible to Buy
Federal law sets two age floors. You must be at least 21 to buy a handgun from a licensed dealer, and at least 18 to buy a rifle or shotgun.1Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts Some states set higher minimums, so check yours before you go.
Federal law also bars several categories of people from possessing firearms at all. A licensed dealer cannot sell you a gun if any of the following applies:
- You’ve been convicted of any crime punishable by more than one year in prison, or you’re currently under indictment for one.
- You’re a fugitive from justice.
- You unlawfully use or are addicted to a controlled substance.
- A court has adjudicated you as mentally incompetent, or you’ve been involuntarily committed.
- You’re in the country illegally, or you’re on a nonimmigrant visa (with limited exceptions such as a valid hunting license).
- You received a dishonorable discharge from the military.
- You’ve renounced your U.S. citizenship.
- You’re subject to a qualifying domestic violence restraining order issued after a hearing.
- You’ve been convicted of a misdemeanor crime of domestic violence.
These categories come directly from federal statute and apply nationwide.1Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts The background check the dealer runs is designed specifically to screen for them.2Federal Bureau of Investigation. About NICS
Bring a valid government-issued photo ID that shows your name, date of birth, current residential address, and photograph. A driver’s license or state ID card from the state where you live is the standard. If your ID doesn’t show your current address, you can supplement it with another government-issued document that does. Active-duty military members can use permanent change-of-station orders alongside a military photo ID to establish state residency.3Bureau of Alcohol, Tobacco, Firearms and Explosives.

Choosing a Firearm That Fits You
The right first firearm depends on what you plan to do with it. Handguns are the most common choice for self-defense and home protection. Rifles suit hunting and long-range target shooting. Shotguns work for home defense, bird hunting, and clay sports.
For a first handgun, most instructors point new buyers toward a 9mm. Ammunition is widely available, recoil is manageable for most people, and it’s the standard caliber used by law enforcement. If recoil is a concern, .22 LR is an excellent training round with almost no kick, though it isn’t a serious self-defense option. For a revolver, .38 Special has mild recoil and simple operation. Save larger calibers like .45 ACP or .357 Magnum until you’ve built shooting experience and hand strength.
Before committing, visit a range that rents firearms. Handling a gun in person tells you what a spec sheet can’t: whether the grip fits your hand, whether you can work the slide or action, and whether the recoil is tolerable after a full magazine. A twenty-dollar rental can save you from buying a gun you end up selling six months later.
Check Whether Your State Requires a Permit First
Federal rules are the baseline. About a dozen states require you to obtain a permit or license before you can buy a firearm at all. Some cover only handguns; others cover all firearms. The process typically involves an application, a fee, and a state-level background check, and some states require fingerprinting. Processing can take days or weeks.
A few states go further and require a Firearm Owner’s Identification card just to possess a gun or buy ammunition. If your state has a permit-to-purchase or owner ID requirement and you skip it, the dealer will turn you away regardless of your federal eligibility. Your state police or public safety agency, along with the ATF, are the reliable sources for current requirements. Handle this well before your planned purchase date.
The Purchase at the Counter
Find a Licensed Dealer
All new firearms and most used firearms sold commercially go through a Federal Firearms Licensee: gun shops, sporting goods stores, and pawn shops authorized by the ATF to sell guns. You cannot legally buy a firearm at a store from someone who doesn’t hold this license.3Bureau of Alcohol, Tobacco, Firearms and Explosives. Federal Firearms Licensee Quick Reference and Best Practices Guide
Fill Out ATF Form 4473
Once you’ve selected a firearm, the dealer hands you ATF Form 4473, the Firearms Transaction Record. The form asks for your full name, address, date of birth, height, weight, race, ethnicity, citizenship, and Social Security number. The SSN is optional, but providing it reduces the chance of a mistaken identity flag. After the personal information comes a series of yes-or-no eligibility questions that mirror the prohibited-persons categories. You sign under penalty of perjury. Lying on the form is a federal felony.3Bureau of Alcohol, Tobacco, Firearms and Explosives. Federal Firearms Licensee Quick Reference and Best Practices Guide
Pass the NICS Background Check
The dealer then contacts the FBI’s National Instant Criminal Background Check System. NICS screens your information against criminal records, mental health adjudications, and other disqualifying data. Most checks come back within minutes with one of three responses: proceed, delayed, or denied.2Federal Bureau of Investigation. About NICS
A “proceed” means you can complete the purchase, subject to any state waiting period. A “delayed” means the FBI needs more time. Under the Brady Act, if the FBI can’t resolve a delay within three business days, the dealer may legally complete the transfer, though some states override this and require the dealer to wait for a definitive answer.2Federal Bureau of Investigation. About NICS Buyers under 21 face a longer window. The Bipartisan Safer Communities Act of 2022 added an extended review period of up to 10 business days for buyers aged 18 to 20, giving the FBI time to check juvenile records.1Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts
A completed NICS check is valid for 30 calendar days. If you don’t pick up the firearm within that window, the dealer has to run the check again.4eCFR. 27 CFR 478.102 – Sales or Deliveries of Firearms on and After November 30, 1998
State Waiting Periods
Roughly a dozen states and the District of Columbia impose mandatory waiting periods between payment and pickup. These range from 72 hours to 14 days depending on the state, and some apply only to handguns while others cover all firearms. The federal background check and the state waiting period run independently. Even if NICS clears you in two minutes, you still wait out the full state-mandated period.
If You’re Denied
A denial means the background check found a disqualifying record. Sometimes those records are wrong or belong to someone with a similar name. You have the right to challenge a denial. The preferred method is an electronic appeal through the FBI’s CJIS Division portal. You’ll need the NICS Transaction Number or State Transaction Number from your denied check, and you should explain what information you believe is inaccurate. You can also mail a written challenge to the FBI CJIS Division in Clarksburg, West Virginia. The FBI is required to respond within 60 calendar days with a decision to sustain or overturn the denial.5Federal Bureau of Investigation. Challenges / Appeals – Requesting Reason for and/or Challenging a NICS-Related Denial
Buying Online or From a Private Seller
You can buy a firearm from an online retailer, but it cannot be shipped to your house. Federal law requires the seller to ship it to a licensed dealer near you. You then go to that dealer, fill out Form 4473, and pass the background check just like an in-store purchase. The receiving dealer typically charges a transfer fee in the $25 to $50 range. Factor that into the price when comparing online deals to your local shop.3Bureau of Alcohol, Tobacco, Firearms and Explosives. Federal Firearms Licensee Quick Reference and Best Practices Guide
Federal law currently does not require a background check when two unlicensed individuals in the same state complete a private sale.1Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts Two qualifications narrow that gap. A growing number of states require all sales, including private ones, to go through a licensed dealer. And the Bipartisan Safer Communities Act of 2022 broadened the federal definition of who is “engaged in the business” of dealing firearms; if you buy and sell guns with any regularity, or buy them intending to resell for profit, you likely need a federal license.6Bureau of Alcohol, Tobacco, Firearms and Explosives. Definition of Engaged in the Business as a Dealer in Firearms
A private seller in one state cannot legally transfer a firearm directly to a buyer in another state. The gun has to go through a licensed dealer in the buyer’s state.7ATF eRegulations. 27 CFR 478.99 – Certain Prohibited Sales, Purchases, or Deliveries Even where private sales are allowed without a background check, you are still forbidden from selling to anyone you know or reasonably suspect is prohibited from owning a firearm. When in doubt, routing a private sale through an FFL is the safest approach for both parties.
Never Buy a Gun for Someone Else
A straw purchase is buying a firearm on behalf of another person, particularly someone who cannot pass a background check on their own. It is a federal crime, and it carries up to 15 years in prison and a $250,000 fine.8Bureau of Alcohol, Tobacco, Firearms and Explosives. Don’t Lie for the Other Guy The first question on Form 4473 asks whether you are the actual buyer. Answering “yes” when you’re buying for someone else is what triggers the crime. Buying a gun as a genuine gift is legal. Buying a gun because someone handed you cash and told you what to get is not.
After You Own It
Store It Safely
About half of all states have child access prevention laws that impose criminal liability if a minor gains access to an unsecured gun. Even in states without such laws, a stolen or mishandled firearm creates serious legal exposure.
A full-size gun safe is the standard, especially if you plan to own more than one firearm. For a single handgun, a small biometric or combination lockbox offers quick access while keeping the gun out of unauthorized hands. Cable locks, which thread through the action to prevent firing, are a minimal-cost backup and are often included free with a firearm purchase. At bare minimum, store firearms unloaded with ammunition separate, and keep keys or combinations away from anyone who shouldn’t have access, especially children.
Get Trained
A basic handgun or rifle course from a certified instructor covers grip, stance, sight alignment, trigger control, and malfunction clearing. Just as importantly, it covers when and how you can legally use a firearm in self-defense. Many ranges offer beginner classes for under $100. Poor habits formed early are hard to correct later, and a negligent discharge is something you can’t take back.
Understand Carry and Transport Rules
Buying a gun and legally carrying it in public are two different things. More than half of all states now allow permitless concealed carry for residents who can legally own a firearm. In the rest, you’ll need a concealed carry permit, which typically requires a training course, an application, a background check, and a fee. Even in permitless-carry states, certain locations are off-limits by law, including courthouses, schools, and federal buildings. Reciprocity across state lines is uneven; not every state honors every other state’s permit.
Federal law protects your right to transport a firearm between any two places where you can legally possess it, as long as the gun is unloaded and neither the firearm nor the ammunition is readily accessible from the passenger compartment. If your vehicle has no separate trunk, both must be in a locked container that isn’t the glove compartment or center console.9Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms State and local rules can be significantly stricter. If you plan to fly, TSA requires the firearm to be unloaded, packed in a locked hard-sided container, and declared to the airline at the ticket counter. Only you should have the key or combination.10Transportation Security Administration. Transporting Firearms and Ammunition
