Large-Capacity Magazine Attorney in Edison and New Brunswick, Middlesex County
Reviewed by William A. Proetta, Esq. · Updated October 2026
Knowingly possessing an ammunition magazine that can hold more than 10 rounds is a 4th-degree crime in New Jersey under N.J.S.A. 2C:39-3(j), with up to 18 months in prison and a fine of up to $10,000. The charge is not on the Graves Act list and carries no mandatory minimum on its own, though it often appears alongside gun charges that do.
Because it is indictable, a magazine count from a stop in Woodbridge, Old Bridge or South Plainfield is screened by the Middlesex County Prosecutor’s Office and, if it is not resolved earlier, heard in the Superior Court in New Brunswick. We handle these cases from our Edison office. Many of the people I represent on magazine charges are lawful gun owners or visitors who bought the magazine legally somewhere else, and their cases call for a different approach than a street-gun prosecution.
What the State Must Prove
- The item is a large-capacity magazine. N.J.S.A. 2C:39-1(y) defines it as a box, drum, tube or other container capable of holding more than 10 rounds. An attached tubular device that holds only .22-caliber rimfire ammunition is excluded.
- The defendant possessed it. Actual possession (in a pocket or a gun) or constructive possession (in a car console, a range bag or a closet the person controls).
- Knowledge. The defendant knew the magazine was there. The State does not have to prove the person knew New Jersey’s limit.
The limit has been 10 rounds since P.L.2018, c.39 lowered it from 15. Selling, transporting or otherwise disposing of these magazines is a separate 4th-degree crime under N.J.S.A. 2C:39-9(h), covered on our page on unlawful sale and trafficking.
Exemptions Written Into the Statute
The exceptions are narrow and specific:
- Registered competition use. A person who registered an assault firearm under N.J.S.A. 2C:58-12 may keep a magazine maintained and used for competitive shooting matches sanctioned by the Director of Civilian Marksmanship of the U.S. Army.
- The 15-round registration. A person who registered a firearm under N.J.S.A. 2C:39-20 whose fixed or detachable magazine holds up to 15 rounds.
- Military and law enforcement. Members of the Armed Forces or National Guard acting under orders, and law enforcement officers, including off-duty officers carrying magazines of 17 rounds or fewer, or larger magazines used with an employer-issued service weapon. A separate statute, N.J.S.A. 2C:39-17, lets a retired officer authorized to carry a handgun under 2C:39-6(l) carry magazines of up to 15 rounds for a semi-automatic handgun.
- Licensed dealers. Magazines kept at the licensed premises for sale to other dealers, the military or police agencies.
There is no general exemption for a gun owner’s home, for range use outside a sanctioned match, or for a nonresident passing through.
Is the magazine legal in New Jersey?
N.J.S.A. 2C:39-1(y), 2C:39-3(j) and 2C:39-17. The limit has been 10 rounds since P.L.2018, c.39 lowered it from 15.

How Magazine Charges Are Graded
How magazine charges are graded, most serious first
N.J.S.A. 2C:39-3(j), 2C:39-9(h) and 2C:39-5(b)(1). Bars run from zero to the top of each ordinary range on a 0 to 10 year scale.
When the magazine is the only charge, a first offender has a presumption against prison at 4th degree. The 10-round limit is being challenged in federal court; the statute remains in the code as written.
The magazine count rarely decides the outcome when a handgun charge is also pending. If the gun was carried without a permit, the Graves minimum on that count, explained in our Graves Act guide, controls the plea math. When the magazine is the only charge, the exposure looks very different: a first offender has a presumption against prison at 4th degree, as our overview of fourth-degree crimes describes.
The Federal Challenge
New Jersey’s 10-round magazine limit is being challenged in federal court, alongside the state’s assault-firearm provisions. The statute remains in the code and we describe it here as written. Litigation of this kind can change the law quickly, so anyone charged should get current advice about where the case stands before deciding how to respond to the charge.
Consequences Beyond the Sentence
- Firearms rights. Even a 4th-degree conviction is a crime that disqualifies the holder from a purchaser card and permits under N.J.S.A. 2C:58-3(c); with up to 18 months of exposure, it can also trigger the federal possession ban. For a lawful owner, that is often the consequence that matters most.
- Immigration. Federal law can treat a firearm conviction as a separate removal ground. A non-citizen should get immigration advice before any plea.
- Expungement. A magazine conviction is eligible for expungement after the usual waiting period.
Magazine Cases in Middlesex County
Most of these charges begin with a car stop on the Turnpike, the Parkway, Route 1 or I-287, where an officer sees a holster or range bag, asks about weapons, and finds a pistol with a 15- or 17-round magazine, often purchased lawfully in the driver’s home state. Even lawful owners are normally charged on a complaint-warrant rather than a summons, so the person is held at the Adult Correction Center in North Brunswick until a first appearance, which runs by video at 2:30 p.m., Monday through Saturday. With an illegal street gun, prosecutors often move to detain and release can be very hard to win; a lawful owner’s case is argued on very different facts.
The Prosecutor’s Office then reviews the facts closely, especially for out-of-state owners. In my experience the MCPO examines whether the gun and magazine were being carried in a way that was legal under the person’s home-state law and the federal transport rules, and if anything about that is questionable, it will normally not agree to Pretrial Intervention. At 4th degree, admission to PTI turns on whether the prosecutor recommends it, and the filing window closes at the Initial Case Disposition Conference. We gather purchase records, travel details and proof of lawful ownership early, before the case reaches a grand jury. Visitors should also read our page for out-of-state gun owners, and hollow points found in the same bag are a separate 4th-degree count discussed on our hollow point page.

Defending a Large-Capacity Magazine Charge
- The stop and search. A magazine found during an unlawful stop, an expanded detention or a warrantless car search can be suppressed. Our guide to car searches explains the roadside rules.
- Capacity. The State must prove the magazine can actually hold more than 10 rounds. Altered, damaged and mislabeled magazines are tested, not assumed.
- Knowledge and control. In a shared or borrowed car, a magazine in a closed bag is not automatically the driver’s.
- Statutory exemptions. Registration records, military orders or law enforcement status can end the case.
- Context. A lawful owner with a clean record and a home-state purchase receipt is in a different position at plea negotiations than the charge sheet suggests.
Large-Capacity Magazine FAQs
How many rounds can a magazine hold in New Jersey?
Ten. A magazine capable of holding more than 10 rounds is a large-capacity magazine under 2C:39-1(y), apart from attached tubular devices for .22 rimfire ammunition.
Is having a 15-round magazine a Graves Act offense?
No. Possession under 2C:39-3(j) is a 4th-degree crime with no mandatory minimum. A handgun charge in the same case may carry one.
Can I keep a high-capacity magazine at home in New Jersey?
Generally not. The statute has no home exemption; the exceptions cover registered competition use, the 15-round registration under 2C:39-20, the military, law enforcement (including qualified retired officers, up to 15 rounds) and licensed dealers.
Is the 10-round magazine limit still in effect?
The statute remains in the code, but it is being challenged in federal court, and the law can change quickly. Get current advice about the status of that litigation.
I was driving through Middlesex County with a magazine bought legally in another state. What happens next?
Expect a complaint-warrant and a close review by the Prosecutor’s Office of whether your transport was legal at home and under federal rules. If anything is questionable, the MCPO normally will not agree to PTI, so early preparation matters.
Where will a Woodbridge or Edison magazine case be heard?
The charge is indictable, so it is screened by the county prosecutor and heard in the Superior Court in New Brunswick rather than the township municipal court.
