Magazine Capacity Limits by State: A 2026 Guide for Travelers, Movers, and Owners

Magazine capacity restrictions are the most quietly enforced firearm laws in the country. Most gun owners understand which states restrict handguns, "assault weapons," and concealed carry permits. Fewer understand which states restrict magazine capacity — and among those, fewer still understand what happens when they travel with, transport through, or move into a restrictive state carrying magazines that were legal where they bought them.

The stakes are real: possessing a standard-capacity magazine in the wrong state can be a felony. Not a fine, not a citation — a felony carrying prison time in several jurisdictions. This guide covers the 2026 landscape, the transport rules, and what changes when you cross a state line.

The states with magazine capacity restrictions

As of 2026, twelve states plus the District of Columbia impose some form of magazine capacity limit on ordinary rifles and handguns:

**10-round limit:** California, Connecticut, Delaware, District of Columbia, Hawaii, Illinois, Maryland (some categories), Massachusetts, New Jersey, New York, Oregon, Vermont (long guns only), Washington

**15-round limit:** Colorado (with some categories at 10)

State laws have moved substantially in the past several years, both in the direction of new restrictions and, through federal court rulings, in the direction of striking down existing ones. Illinois' Protect Illinois Communities Act has been the subject of extended Seventh Circuit litigation. California's magazine ban has cycled through Ninth Circuit rulings. Washington and Delaware are newer additions.

The practical implication: always verify current law before traveling with or transporting magazines through any of these jurisdictions. This article reflects the general landscape as of 2026, but statutes and injunctions change.

Grandfathered vs. prohibited: the two-tier problem

Most magazine restriction laws distinguish between magazines lawfully owned before the effective date (often "grandfathered" and legal to keep) and magazines acquired after (prohibited). This creates a two-tier system that is confusing at the state line and dangerous at the traffic stop.

- **Grandfathered possession** typically means the magazine was owned in-state before the law took effect. Bringing a magazine into the state that would be grandfathered if you'd lived there is not the same thing. - **Acquired after the effective date** is generally prohibited regardless of where or when purchased. - **Newly moving into the state** with previously legal magazines — some states permit them under grandfather rules, some require registration within a defined window, some require surrender or out-of-state removal.

The consequence: a resident of Nevada with a 30-round AR-15 magazine, who moves to California, does not automatically get grandfathered rights. That magazine may need to be surrendered, sold out of state, permanently modified, or removed from California before the move.

Traveling through restrictive states — and why safe-passage law doesn't fully protect you

The federal Firearm Owners Protection Act at 18 U.S.C. § 926A provides limited safe-passage protection for firearms transported through states that would otherwise prohibit their possession. That protection covers the firearm — unloaded, in a locked container, separate from ammunition, being transported between two places where possession is legal.

Critically, § 926A has been read narrowly on magazine capacity. Courts have generally held that:

- The safe-passage protection applies to firearms, not necessarily to their component parts and accessories in the same clean-cut way. - A traveler stopped in a restrictive state with prohibited-capacity magazines separate from the firearm may still face state charges on the magazines themselves. - The protection requires no unnecessary stops in the restrictive state. Overnight hotel stays, extended detours, and stops at anything other than fuel/food/rest have been used to argue the transport was not truly "in progress."

The practical implication for interstate travel with standard-capacity magazines:

- If your route can avoid restrictive states, avoid them - If it can't, transport magazines locked, empty, and separate from the firearm — same treatment as the firearm itself - Don't make overnight stops in restrictive states while carrying prohibited-capacity magazines - Understand that the safe-passage argument on magazines specifically is weaker than the argument on the firearm itself

Moving into a restrictive state

The move scenario is where most well-meaning owners get in trouble. A resident of a permissive state accepts a job offer in a restrictive state, packs the moving truck, and doesn't think about the box of AR-15 magazines and Glock 19 magazines in the safe. Then the state DMV registration and mail-forward creates a record of the move, and the magazines are in the wrong state.

Your options before the move:

- **Verify the destination state's grandfather rules** — some permit continued possession of previously acquired magazines by new residents; many do not. - **Sell out of state before moving**, either privately in your current state or through a firearms auction house that ships to buyers in other permissive states. - **Convert or permanently modify** where the state's statute allows — this is limited and technical; check state guidance. - **Store out of state** with a friend or family member in a permissive state, or in a commercial firearms storage facility. - **Surrender** to law enforcement in the destination state if the magazines cannot be lawfully brought in.

Waiting until after the move to figure this out is the wrong sequence. The magazines are contraband the moment residence changes, and moving-truck records, utility hookups, and DMV updates all establish that date on paper.

Handguns, rifles, shotguns, and shotgun tube extensions

Not all magazine capacity restrictions apply uniformly across firearm types. Common variations:

- Some states restrict rifle magazines but not handgun magazines, or vice versa - Some states specifically address tube-fed shotgun capacity through separate statutes - "Fixed" vs. "detachable" magazine distinctions matter in some states (California's featureless/fixed-magazine builds are one example) - Compliance-parts markets exist for restrictive states (10-round Magpul PMAGs, blocked Glock magazines) — but the compliance market for one state is often noncompliant in another

Read the specific statute for the specific firearm you're transporting. Do not assume the rifle rule applies to the handgun rule or vice versa.

The court rulings that keep changing the landscape

Several federal appellate cases in 2024-2026 have addressed magazine capacity restrictions post-Bruen:

- The Ninth Circuit's *Duncan v. Bonta* proceedings on California's magazine ban have run through multiple opinions and en banc reviews. - The Seventh Circuit has reviewed the Illinois Protect Illinois Communities Act, including its magazine limits. - Several district courts have entered and lifted preliminary injunctions on state laws pending appeal.

The consequence for owners and travelers: what was blocked six months ago may not be blocked today, and vice versa. Never rely on old news coverage or a friend's understanding of the current state of the law. Check the current statute and any active injunctions before transporting.

What to do before crossing any restrictive state line

Five concrete steps:

1. **Identify every magazine you're transporting** and its capacity. Standard-capacity for one firearm may be over-capacity for another. 2. **Check the destination state and every state you'll transit** for current magazine restrictions. 3. **Locate the specific statute**, not a summary — state legislature websites and state attorney general publications are authoritative. 4. **Plan the route to avoid restrictive states** where possible. When it's not possible, plan to minimize stops. 5. **Transport prohibited-capacity magazines the same way you transport the firearm** — unloaded, locked, separated from ammunition — even though the safe-passage law's protection is weaker on magazines.

A traveler who does all five will almost never be the one charged. A traveler who assumes federal law fully protects them across state lines is the one who gets a lesson in state supremacy on possession offenses.

Frequently Asked Questions

### Which states have magazine capacity limits in 2026?

Twelve states plus the District of Columbia currently impose magazine capacity restrictions on ordinary rifles and handguns: California, Colorado, Connecticut, Delaware, DC, Hawaii, Illinois, Maryland (certain categories), Massachusetts, New Jersey, New York, Oregon, Vermont (long guns only), and Washington. Most set the limit at 10 rounds; Colorado uses 15 for some categories. Laws and active injunctions change — always verify the current statute before relying on this list.

### Does federal safe-passage law protect me if I'm transporting standard-capacity magazines through a restrictive state?

Only partially, and less than most travelers assume. 18 U.S.C. § 926A protects transportation of an unloaded firearm in a locked container, separate from ammunition, through a restrictive state — but courts have been more restrictive in extending that protection to magazines separately from the firearm. Travelers stopped with prohibited-capacity magazines in transit have faced state charges. Transport magazines the same way you transport the firearm, and minimize any stops.

### What happens if I move to California with 30-round AR-15 magazines that were legal in my old state?

Those magazines are generally prohibited to possess in California under the state's magazine ban, and moving into the state does not create a grandfather right — the grandfather rights typically apply only to magazines owned in California before the effective date. Before the move: sell out of state, permanently modify where the statute permits, store with a friend or family member in a permissive state, or surrender to law enforcement in California. Bringing them in and then figuring it out is contraband possession.

### Are 10-round or reduced-capacity magazines legal to buy nationally?

Yes. Compliance-market magazines (10-round PMAGs, blocked or pinned magazines) are sold nationally and are legal in every state that restricts capacity. A traveler moving between a permissive and a restrictive state can maintain compliant magazines specifically for use in the restrictive state.

### If I'm moving out of a restrictive state, can I take my grandfathered magazines with me?

Once you cross into a permissive state, the destination state's law governs. Grandfathered magazines you owned lawfully in-state generally become fully legal in a permissive destination state. The restrictive-state grandfather status becomes irrelevant once you're no longer subject to that state's law. Sale, purchase, and possession are then governed by the new state's rules.
