To purchase a gun in New Mexico, you must be old enough under federal law (18 for a long gun, 21 for a handgun from a dealer), pass an FBI background check, wait seven calendar days, show a valid government photo ID, and not fall into any federal or state category of prohibited persons. There is no state permit or license to buy, but the background-check and waiting-period rules apply to private sales too, not just purchases from a licensed dealer.
Age Minimums
Federal law sets the floor, and New Mexico does not raise it. From a licensed dealer, you must be at least 18 to buy a rifle or shotgun and at least 21 to buy a handgun.1Bureau of Alcohol, Tobacco, Firearms and Explosives. Minimum Age for Gun Sales and Transfers Private, unlicensed sellers face no federal minimum age for a rifle or shotgun transfer, but the state’s background-check requirement still applies to those sales.
Who Cannot Buy a Firearm
Federal law bars nine categories of people from receiving or possessing firearms. The ones that come up most often at the counter are:
- Anyone convicted of a crime punishable by more than one year in prison.
- Anyone convicted of a misdemeanor crime of domestic violence.
- Anyone subject to a qualifying protective order restraining them from threatening or harassing an intimate partner or child.
- Anyone adjudicated as mentally defective or involuntarily committed to a mental institution.
- Anyone who is an unlawful user of, or addicted to, a controlled substance.
- Fugitives from justice.
- Anyone dishonorably discharged from the military.
- Anyone who has renounced U.S. citizenship.
- Most people admitted on a nonimmigrant visa, with limited exceptions.
New Mexico’s Additional Prohibitions
State law adds another layer. Under NMSA 30-7-16, you cannot receive, transport, or possess a firearm in New Mexico if you are a felon, if you are under a protective order issued under the Family Violence Protection Act or the Harassment and Stalking Act, or if you have been convicted of battery against a household member, criminal damage to a household member’s property, or a first stalking offense. Possession by a felon is a third-degree felony; for others covered by the statute, violating it is a misdemeanor.2Justia.

ID and the Paperwork at the Counter
Every purchase from a licensed dealer runs through ATF Form 4473. The form asks for your full legal name, date of birth, place of birth, and physical description. A Social Security number is technically optional, but supplying it helps the background-check system tell you apart from other people with similar names and can prevent a delay.3Bureau of Alcohol, Tobacco, Firearms and Explosives. Firearms Transaction Record
You need a valid government-issued photo ID showing your name, photograph, and date of birth. A New Mexico driver’s license or state ID is the standard. If the ID does not show your current residential address, you can supplement it with another valid government-issued document that does, such as a tax document or a government electronic record with your name and address. The dealer records both.3Bureau of Alcohol, Tobacco, Firearms and Explosives. Firearms Transaction Record Lying on the form is a federal crime, and the form itself warns that certain Gun Control Act violations carry up to 15 years in prison and a $250,000 fine.4Bureau of Alcohol, Tobacco, Firearms and Explosives.

Non-Citizen Buyers
Lawful permanent residents buy on the same terms as U.S. citizens. Nonimmigrant aliens (tourists, students, temporary workers) face tighter rules: a nonimmigrant alien who has established residency in New Mexico can buy from a dealer or private seller if all other requirements are met, but a nonimmigrant alien without U.S. residency generally cannot take possession of a firearm domestically. People admitted under the Visa Waiver Program are treated separately and may lawfully possess firearms during their stay.5Bureau of Alcohol, Tobacco, Firearms and Explosives. Firearms Questions and Answers
Background Check and Seven-Day Wait
Every firearm sale in New Mexico requires a check through the FBI’s National Instant Criminal Background Check System (NICS). The dealer submits your information, and NICS screens for disqualifying convictions, protective orders, and mental health adjudications.
New Mexico also imposes a seven-calendar-day waiting period before the dealer can hand over the gun. The law, at NMSA 30-7-7.3, took effect May 15, 2024.6Bureau of Alcohol, Tobacco, Firearms and Explosives. Open Letter to All New Mexico Federal Firearms Licensees Calendar days, not business days. Weekends and holidays count.
The waiting period and the background check run at the same time. If NICS clears you on day two, you still wait until day seven to pick up the firearm. If NICS has not returned an answer by day seven, the dealer cannot release the firearm until the check is finished. If 20 full days pass without a completed check, the dealer may transfer it at that point.7Justia. New Mexico Code 30-7-7.3 – Unlawful Sale of a Firearm Before Required Waiting Period Ends The dealer keeps the firearm the whole time.
The 20-day rule matters. Under federal defaults, a dealer can proceed after three business days when NICS has not answered. New Mexico overrides that. You cannot walk out on day four the way a buyer in another state might. A dealer who releases a firearm before the waiting period ends commits a misdemeanor under state law.
When the Waiting Period Does Not Apply
The seven-day wait is waived if you hold a valid federal firearms license (FFL) or a valid New Mexico concealed handgun license. It also does not apply to sales to a law enforcement agency, to transfers between certified law enforcement officers, or to sales between immediate family members. The statute defines immediate family broadly: spouse, parent, child, sibling, grandparent, grandchild, great-grandchild, niece, nephew, first cousin, aunt, or uncle.7Justia. New Mexico Code 30-7-7.3 – Unlawful Sale of a Firearm Before Required Waiting Period Ends Even when the wait is waived, a background check still applies to any sale that goes through a dealer.
Buying From a Private Seller
New Mexico requires background checks on private sales, not just dealer sales. If you buy from another individual, the seller must arrange for a licensed dealer to run the NICS check before the transfer is completed. The dealer can charge up to $35 for that service, which is the statutory cap.8Justia. New Mexico Code 30-7-7.1 – Unlawful Sale of a Firearm Without a Background Check The seven-day waiting period also applies to private sales unless one of the exceptions covers the transaction.
Sales between immediate family members and transfers between law enforcement officers are exempt from the background check itself, not just the wait. Selling a firearm without a required background check is a misdemeanor.
Storage Duties Once You Own It
Buying is only the first step. Under the Bennie Hargrove Gun Safety Act, an adult who negligently leaves a firearm accessible to a minor faces a misdemeanor if the minor brandishes the gun, and a fourth-degree felony if the minor uses it and someone suffers great bodily harm or death.9New Mexico House Democrats. Bennie Hargrove Gun Safety Act Heads to Governor’s Desk Plan for secure storage before you bring a firearm home.
Losing the Right to Buy: Extreme Risk Orders
New Mexico’s extreme risk firearm protection order (ERFPO) law lets a court temporarily strip someone of the ability to buy or possess firearms when they pose a serious danger to themselves or others. Petitions are filed by law enforcement or the district attorney’s office; a concerned family member or other person can act as a “reporting party” through a sworn affidavit.10New Mexico Courts. Extreme Risk Firearm Protection Order If you are served with an ERFPO, the order is entered into the federal background-check database, and you cannot purchase a firearm for as long as it is in effect.
