State Law Summary
Constitution of the State of New Hampshire - N.H. Const. Pt. I, Art. 2-a
All persons have the right to keep and bear arms in defense of themselves, their families, their property, and the state.
New Hampshire's firearm law history has evolved significantly over the years, marked by a series of legal cases and legislative changes that reflect its cultural values surrounding gun ownership. Notably, the New Hampshire Supreme Court's decision in 2005 in State v. Williams reinforced individual rights by clarifying the constitutional basis for carrying concealed firearms. In recent years, laws have shifted toward enhancing gun rights, including the 2017 repeal of the state’s permit requirement for carrying concealed firearms, aligning with the trend of constitutional carry adopted by several states. Moreover, the state has actively resisted attempts to impose restrictions such as enhanced background checks, reflecting a legislative environment that generally supports second amendment rights. Throughout this history, New Hampshire has maintained a distinct identity as a state that values personal freedom and responsibility concerning firearm ownership.
Permit Eligibility, Training and Application Process
In New Hampshire, the regulation of pistol and revolver licenses has undergone significant changes over the years. Originally, in 1967, the state established a system requiring residents to obtain a license to carry a concealed pistol or revolver, governed by RSA 159:4. The process involved a background check and approval by the local police chief or sheriff. However, a major shift occurred in 2017 with the passage of House Bill 500, which removed the requirement for a license to carry concealed firearms for lawful gun owners, essentially making New Hampshire a permitless carry state. Despite this, the state still maintains the option for individuals to obtain a license, primarily for the purposes of reciprocity with other states' concealed carry laws. As of 2021, the landscape continues to evolve as New Hampshire remains a state characterized by its strong support for Second Amendment rights.
New Hampshire law does not require applicants for a license to carry a firearm to undergo firearms safety training or otherwise demonstrate knowledge of firearms safety. . The fee for the New Hampshire License to Carry is $10.00 for New Hampshire residents and the license is valid for not more than five years. The license shall be in duplicate with one copy held by the licensee and one copy held by the issuing officer. The license must be issued within 14 days of application.
I. (a) The selectmen of a town, the mayor or chief of police of a city or a full-time police officer designated by them respectively, the county sheriff for a resident of an unincorporated place, or the county sheriff if designated by the selectmen of a town that has no police chief, upon application of any resident of such town, city, or unincorporated place, or the director of state police, or some person designated by such director, upon application of a nonresident, shall issue a license to such applicant authorizing the applicant to carry a loaded pistol or revolver in this state for not less than 5 years from the date of issue, if it appears that the applicant has good reason to fear injury to the applicant's person or property or has any proper purpose, unless the applicant is prohibited by New Hampshire or federal statute from possessing a firearm. Hunting, target shooting, or self-defense shall be considered a proper purpose. The license shall be valid for all allowable purposes regardless of the purpose for which it was originally issued.
(b) The license shall be in duplicate and shall bear the name, address, description, and signature of the licensee. The original shall be delivered to the licensee and the duplicate shall be preserved by the people issuing the same for 5 years. When required, license renewal shall take place within the month of the fifth anniversary of the license holder's date of birth following the date of issuance. The license shall be issued within 14 days after application, and, if such application is denied, the reason for such denial shall be stated in writing, the original of which such writing shall be delivered to the applicant, and a copy kept in the office of the person to whom the application was made. The fee for licenses issued to residents of the state shall be $10, which fee shall be for the use of the town or city granting said licenses; the fee for licenses granted to out-of-state residents shall be $100, which fee shall be for the use of the state. The director of state police is hereby authorized and directed to prepare forms for the licenses required under this chapter and forms for the application for such licenses and to supply the same to officials of the cities and towns authorized to issue the licenses. The form shall require no more information than was required on the state of New Hampshire application for pistol/revolver license, form DSSP 85, as revised in December 2009. No other forms shall be used by officials of cities and towns. The cost of the forms shall be paid out of the fees received from nonresident licenses.
II. No photograph or fingerprint shall be required or used as a basis to grant, deny, or renew a license to carry for a resident or nonresident, unless requested by the applicant.
III. The availability of a license to carry a loaded pistol or revolver under this section or under any other provision of law shall not be construed to impose a prohibition on the unlicensed transport or carry of a firearm in a vehicle, or on or about one's person, whether openly or concealed, loaded or unloaded, by a resident, nonresident, or alien if that individual is not otherwise prohibited by statute from possessing a firearm in the state of New Hampshire.
N.H. Rev. Stat. § 159:6
Permitless Carry Law
The terms “constitutional carry” and “permitless carry” refer to states that have laws allowing individuals to carry a loaded firearm in public without requiring a license or permit.Â
New Hampshire is a permitless carry state, meaning that a license is not required to carry a concealed or open firearm in public. This law was enacted in 2017. A License to Carry issued from the State of New Hampshire may be required for residents seeking to carry under a reciprocity agreement within another State.
Reciprocity Agreements
Reciprocity refers to an agreement between states to recognize, or honor, a concealed firearm permit issued by another state.
When you are in another state, you are subject to that state’s laws. Even if a state recognizes your carry permit or allows for permitless carry, the state may have additional restrictions on certain types of firearms, magazines, or ammunition. Take time to learn the law!
State Preemption Laws
State firearm preemption laws are statutes that prevent local governments from enacting or enforcing their own gun regulations that are more restrictive than state law. These laws ensure that firearm regulations remain consistent across the state, preventing a patchwork of different rules in various cities or counties.Â
Preemption: Local governments cannot enact laws that regulate the sale, purchase, ownership, use, possession, transportation, licensing, permitting, taxation, or other matters related to firearms.
N.H. Rev. Stat. § 159:26
Purchase/Transfer Laws
When buying or selling a firearm, both federal and state laws must be followed. Under 18 U.S.C. § 922(a)(5), a private party may sell a firearm to a resident of the same state if two conditions are met: (1) the seller and buyer must be residents of the same state, and (2) the seller must not know or have reasonable cause to believe that the buyer is prohibited from receiving or possessing firearms under federal law, as outlined in 18 U.S.C. § 922(g).Â
Additionally, a private seller may loan or rent a firearm to a resident of any state for temporary lawful sporting use, provided they meet the same condition of not knowing or having reason to believe the borrower is prohibited under federal law. Â
In addition to federal law, state laws governing firearm sales must also be followed, as states may impose additional restrictions such as background checks, waiting periods, or bans on specific types of firearms.Â
Firearm Classification and Accessory Restrictions
COMING SOON!
Magazine Capacity Restrictions
Magazine capacity laws are designed to limit the number of rounds a firearm's magazine can hold, typically restricting it to a certain number of cartridges (e.g., 10 rounds or fewer). Some state laws restrict the amount of rounds that may be placed in a magazine at any given time, while others prevent the mere possession of unloaded magazines capable of accepting more than a certain number of rounds.
Prohibited Areas - Where Firearms Are Prohibited Under State law
Carrying a firearm into a place where firearms are prohibited by state or federal law is a common way for gun owners to find themselves in legal trouble. These places are known as “prohibited areas,” and they can vary greatly from state to state.
Below you will find the list of the places where firearms are prohibited under this state’s laws. Keep in mind, in addition to these state prohibited areas, federal law adds additional places where firearms are prohibited. See the federal law section for a list of federal prohibited areas.
In New Hampshire the places you are prohibited by the state from having a gun are in courthouses and courtrooms.
 No person shall knowingly carry a loaded or unloaded pistol, revolver, or firearm or any other deadly weapon as defined in RSA 625:11, V, whether open or concealed or whether licensed or unlicensed, upon the person or within any of the person's possessions owned or within the person's control in a courtroom or area used by a court. Whoever violates the provisions of this paragraph shall be guilty of a class B felony.
For purposes of paragraph I, "area used by a court" means:
(a) In a building dedicated exclusively to court use, the entire building exclusive of the area between the entrance and the courthouse security.
(b) In any other building which includes a court facility, courtrooms, jury assembly rooms, deliberation rooms, conference and interview rooms, the judge's chambers, other court staff facilities, holding facilities, and corridors, stairways, waiting areas, and elevators directly connecting these rooms and facilities.
N.H. Rev. Stat. § 159:19
Methods of Carry - Open Carry Laws
Open carry and concealed carry refer to two distinct methods of carrying firearms in public. Open carry involves visibly carrying a firearm, typically in a holster, where it is easily seen by others. Concealed carry, on the other hand, involves carrying a firearm in a hidden manner, such as under clothing, so that it is not visible to others.
No Weapons Signs
No weapons" signs are notices posted by businesses or private property owners indicating that firearms or other weapons are not allowed on the premises. The legal impact of these signs varies by state. In some states, these signs have the force of law, meaning that if a person carries a weapon onto the property in violation of the sign, they can face criminal penalties such as fines or arrest. In these states, ignoring a "no weapons" sign can result in legal consequences similar to trespassing. Â
In other states, however, these signs are merely a business's policy, and while a person carrying a weapon might be asked to leave, there are no legal penalties for entering with a weapon unless they refuse to leave when asked, at which point trespassing laws may apply.Â
 In New Hampshire a “No Firearms” sign posted on private property does not carry the weight of law but they can ask you to leave if you’re carrying, and have you arrested for trespassing if you refuse to leave. You will not have violated New Hampshire law related to carrying a firearm but you will be violating their company policy and NH trespassing statutes if you don’t leave when you are asked.
Controlled Substance/Alcohol Laws
Most, but not all, states have laws in place that regulate possessing firearms while intoxicated, and individual states will define "intoxicated" differently. In addition to state law, federal law also prohibits the possession of a firearm by any person who is “an unlawful user of or addicted to any controlled substance” as defined by the Controlled Substances Act (“CSA”). There are five different schedules of controlled substances regulated by the CSA, scheduled as I–V. The types of drugs that are regulated range from heroin as a Schedule I substance, to Robitussin AC as a Schedule V substance. Even a gun owner that is prescribed a scheduled drug by a physician can be in legal jeopardy if it is proven that the drug was taken in a frequency or manner other than was prescribed. Â
Although legal for medicinal or recreational use in many states, marijuana remains classified as a scheduled controlled substance under the federal Controlled Substances Act (CSA), codified as 21 U.S.C. § 812. On May 16, 2024, the U.S. Department of Justice published a proposed rule change that would reclassify marijuana from schedule I to a schedule III drug. It is anticipated this rescheduling will formally occur in 2024 or 2025. Unlike schedule I drugs, schedule III drugs may be lawfully prescribed by a licensed physician, and thus the possession of these prescribed drugs does not make the possession of a firearm inherently unlawful the way possession of a schedule I substance would. This means that the rescheduling of marijuana to a schedule III drug would finally allow for the lawful use, possession and purchase of firearms by prescription marijuana users. However, if it is determined that the marijuana is possessed without a prescription, is used in a manner that is not prescribed, or that the individual with the prescription is addicted to marijuana, possession of a firearm would still be a federal offense. Federal law states that a person is addicted to a controlled substance when they have “lost the power of self-control with reference to the use of controlled substance; and any person who is a current user of a controlled substance in a manner other than as prescribed by a licensed physician.” Â
27 C.F.R. § 478.11, 18 U.S.C. §922(g)(3)Â
Vehicle and Transport Laws
Permit reciprocity and other differences between state regulation of firearms can create a difficult landscape for firearm owners to navigate while transporting firearms interstate. In 1968, and again in 1986, Congress set out to help hunters, travelers, and other firearm owners who were getting arrested for merely transporting firearms through restrictive states. To help simplify the complex web of state firearm laws, Congress passed the 1986 Firearm Owners Protection Act (“FOPA”) as part of Senate Bill 2414. The specific “safe harbor” provision of the law, often referred to as the “McClure-Volkmer Rule,” provides some protection for gun owners transporting firearms through restrictive states, subject to strict requirements. This federal law is covered in more detail in the federal law section of this database.
Beyond federal law, the laws of each state will impose additional restrictions, or protections, related to transporting firearms in a vehicle.
Storage Requirements
Some states have laws that require gun owners to take specific measures to secure their firearms, especially in households with children. Many of these state laws mandate that guns be stored in locked containers or safes when not in use. These laws often impose penalties for failing to secure firearms, particularly if they are accessed by unauthorized individuals, such as minors.
Other Weapons Restrictions

Police Encounter Laws
Some states impose a legal duty upon permit holders that requires them to inform a police officer of the presence of a firearm whenever they have an official encounter, such as a traffic stop. These states are called “duty to inform” states. In these states you are required by law to immediately, and affirmatively, tell a police officer if you have a firearm in your possession.
In addition to “duty to inform states,” some states have “quasi duty to inform” laws. These laws generally require that a permit holder have his/her permit in their possession and surrender it upon the request of an officer. The specific requirements of these laws will vary from state to state.
The final category of states is classified as “no duty to inform” states. In these states there are no laws that require a gun owner to affirmatively inform an officer if they have a firearm. Additionally, there are also generally no laws that require you to respond or provide a permit if asked about the presence of a firearm.
Red Flag or Emergency Risk Orders
Emergency Risk Orders (or "Red Flag Laws") enable rapid legal action when someone is believed to be at significant risk of harming themselves or others with a firearm. Generally speaking, these controversial laws allow law enforcement to seek a court order to temporarily confiscate firearms from the individual and prevent them from purchasing new ones while the order is in effect. The most robust laws also permit family members and others to file petitions.
Use of Force in Defense of Person
The legal use of force, including deadly force, is regulated by state law. There are no federal laws that dictate when you can use force in self-defense in all states. As such, it is essential to become familiar with individual state laws.
I. A person is justified in using non-deadly force upon another person in order to defend himself or a third person from what he reasonably believes to be the imminent use of unlawful, non-deadly force by such other person, and he may use a degree of such force which he reasonably believes to be necessary for such purpose. However, such force is not justifiable if:
(a) With a purpose to cause physical harm to another person, he provoked the use of unlawful, non-deadly force by such other person; or
(b) He was the initial aggressor, unless after such aggression he withdraws from the encounter and effectively communicates to such other person his intent to do so, but the latter notwithstanding continues the use or threat of unlawful, non-deadly force; or
(c) The force involved was the product of a combat by agreement not authorized by law.
II. A person is justified in using deadly force upon another person when he reasonably believes that such other person:
(a) Is about to use unlawful, deadly force against the actor or a third person;
(b) Is likely to use any unlawful force against a person present while committing or attempting to commit a burglary;
(c) Is committing or about to commit kidnapping or a forcible sex offense; or
(d) Is likely to use any unlawful force in the commission of a felony against the actor within such actor's dwelling or its curtilage.
N.H. Rev. Stat. § 627:4
Use of Force in Defense of Others
Defense of third party laws allow an individual to use force, including deadly force, to protect another person from harm. These laws generally permit intervention if the third party would have had the right to use force in their own self-defense under the same circumstances. The exact application of these laws will vary by jurisdiction, so it is important to understand the framework of each individual state.
New Hampshire does not have a law specific to the defense of others, but does allow for the defense of a third person in its defense-of-person law.
Use of Force in Defense of Habitation
The term "castle doctrine" comes from English common law providing that one's abode is a special area in which one enjoys certain protections and immunities, from which one is not obligated to retreat before defending oneself against attack, and in which one may do so without fear of prosecution.
Many states have instituted castle doctrine laws, with varying degrees of formality. Some states have statutorily enacted castle doctrine laws, some have judicially-created protections (called “common laws”), while others have no amplified protections in the home at all.
A person in possession or control of premises or a person who is licensed or privileged to be thereon is justified in using non-deadly force upon another when and to the extent that he reasonably believes it necessary to prevent or terminate the commission of a criminal trespass by such other in or upon such premises, but he may use deadly force under such circumstances only in defense of a person as prescribed in RSA627:4 or when he reasonably believes it necessary to prevent an attempt by the trespasser to commit arson.
N.H. Rev. Stat. § 627:7
Use of Force in Defense of Property
Generally speaking, the use of deadly force is limited to circumstances that reasonably present an imminent threat of serious bodily injury or death of a human being. As such, using deadly force in defense of mere personal property is almost categorically prohibited. Although most states will allow the use of some amount of force (i.e. physically restraining someone until the police arrive), the use or threatened use of deadly force in defense of mere property is generally not permitted.
A person is justified in using force upon another when and to the extent that he reasonably believes it necessary to prevent what is or reasonably appears to be an unlawful taking of his property, or criminal mischief, or to retake his property immediately following its taking; but he may use deadly force under such circumstances only in defense of a person as prescribed in RSA627:4.
N.H. Rev. Stat. § 627:8
Self-Defense Immunity
It is not uncommon for an actor to be defending himself from criminal charges (i.e. second degree murder) and a separate civil lawsuit brought by the family of the deceased attacker. Â
Even if someone is not charged criminally, they can still be sued civilly and the victim of a violent crime who is determined to be criminally justified, could still potentially be sued by their attacker’s family.
[N.H. Rev. Stat. Ann. § 627:4, 62:5, 627:6, 627:7 and 627:1a]
Duty to Retreat
A duty to retreat is an obligation to flee that is imposed upon a civilian who is under attack. If applicable, it applies to the victim of unlawful force prior to their ability to use deadly force to defend him or herself. The duty to retreat makes self-defense unavailable to those who use deadly force when they could have retreated from the confrontation safely. The alternative to duty-to-retreat laws is no-duty-to-retreat laws or stand-your-ground laws as they’re commonly called. Stand-your-ground states impose no duty to flee upon victims and instead state that one can stand their ground and meet force with force, under certain situations.
