What Is the Legal Magazine Capacity in New Jersey?

New Jersey law generally limits firearm magazines to a maximum capacity of 10 rounds of ammunition.

This restriction applies to most magazines used in firearms such as:

  • Handguns
  • Semi-automatic rifles
  • Firearms that use detachable magazines

Magazines capable of holding more than 10 rounds are generally considered prohibited large-capacity ammunition magazines under New Jersey law.

Firearm owners should ensure that any magazines they possess comply with the state’s capacity limit.

History of New Jersey’s Magazine Capacity Limit

New Jersey previously allowed firearm magazines capable of holding up to 15 rounds of ammunition.

However, legislation enacted in 2018 reduced the legal limit to 10 rounds.

After the law changed, firearm owners who possessed magazines exceeding the new limit were required to:

  • Modify the magazines so they could hold no more than 10 rounds
  • Transfer the magazines out of state
  • Sell them to a licensed dealer
  • Surrender them to law enforcement

The change aligned New Jersey with several other states that enforce lower magazine capacity limits.

Magazine Capacity Rules for Handguns

Most semi-automatic pistols use detachable magazines, which fall under the 10-round limit in New Jersey.

Because of this restriction, many handgun manufacturers produce NJ-compliant versions of their firearms that include magazines designed to hold no more than 10 rounds.

Firearm dealers in New Jersey typically sell pistols with magazines that comply with the state’s capacity limits.

Magazine Capacity Rules for Rifles

Many semi-automatic rifles use detachable magazines, and those magazines are also subject to the 10-round capacity limit in New Jersey.

This applies to magazines used in various types of rifles, including modern sporting rifles and other semi-automatic firearms that accept detachable magazines.

When purchasing rifles in New Jersey, firearm owners will typically receive magazines that have been manufactured or modified to comply with the state’s capacity restrictions.

Magazine Capacity Rules for Shotguns

Shotguns may use either detachable magazines or fixed tubular magazines, depending on the firearm design.

  • Shotguns that use detachable magazines are generally subject to the 10-round magazine capacity limit.
  • Many traditional shotguns use tubular magazines located beneath the barrel. These fixed magazines may be treated differently than detachable magazines depending on the firearm configuration.

Because firearm classifications and configurations can vary, gun owners should always confirm that their firearm and magazine setup complies with current New Jersey law.

What Is Considered a Large Capacity Magazine?

Under New Jersey law, a large capacity ammunition magazine is generally defined as a magazine capable of holding more than 10 rounds of ammunition.

This definition typically applies to detachable magazines used in firearms such as:

  • Semi-automatic pistols
  • Semi-automatic rifles
  • Firearms designed to accept detachable magazines

Possessing a prohibited magazine that exceeds the legal capacity limit may result in serious criminal penalties.

Why Magazine Capacity Laws Can Be Confusing

Magazine capacity limits vary significantly between states.

Many states allow magazines capable of holding 15, 17, or even 30 rounds, while New Jersey enforces a stricter limit.

Because of these differences, firearm owners moving to New Jersey or traveling into the state may mistakenly assume their magazines are legal when they are not.

Understanding New Jersey’s capacity limit is important for remaining compliant with state law.

Responsible Firearm Ownership

Responsible gun owners take time to understand the laws governing their firearms and accessories.

Ensuring that magazines comply with New Jersey’s capacity limits helps firearm owners avoid accidental violations of the law.

Gun owners should also familiarize themselves with other important regulations related to firearm transportation, storage, and lawful possession.
