California Magazine Laws Explained (2026)

Last Updated: April 2026

California's magazine capacity laws are confusing, constantly changing, and often misunderstood. This guide breaks down exactly what you can and cannot legally possess.

Current Law: 10-Round Maximum

As of 2026, California Penal Code § 32310 makes it illegal to:

Manufacture
Import
Sell
Give
Lend
Or otherwise transfer

Any magazine that holds more than 10 rounds of ammunition.

However: Possession of large-capacity magazines is currently legal due to ongoing court cases.

What "Large-Capacity Magazine" Means in CA

California defines a "large-capacity magazine" as:

> "Any ammunition feeding device with the capacity to accept more than 10 rounds"

This includes:

Detachable box magazines
Internal/fixed magazines (if they hold >10)
Belt-fed ammunition links (if >10 rounds)
Drum magazines
Even magazines that are permanently blocked to 10 rounds but still look like they hold more

The Legal History (Why It's Confusing)

2000: Original Ban

CA banned magazines over 10 rounds
Grandfathered magazines owned before 2000

2016: Prop 63

Required disposal of grandfathered magazines
Banned possession entirely

2019: Duncan v. Becerra

Federal judge ruled the ban unconstitutional
Possession became legal again
Sales remained banned

2021-2024: Appeals Court

9th Circuit upheld the ban (in part)
Currently being appealed to Supreme Court
Status remains in flux

2026: Current Status

Possession: Legal (for now)
Sales/Transfers: Illegal
Import: Illegal
Manufacture: Illegal

What You CAN Legally Do

✅ Possess Large-Capacity Magazines

If you legally obtained them (before 2000, during freedom week, moved from another state), you can currently possess them.

✅ Use Them at Private Property

You can use 30-round magazines on private property (your land, private ranges that allow it).

✅ Repair Your Magazines

You can replace worn parts (springs, followers) on existing magazines.

✅ Blocked/Pinned 10-Round Magazines

You can use magazines that have been permanently blocked to 10 rounds.

✅ "Freedom Week" Magazines

If you acquired magazines during "Freedom Week" (March 29-April 5, 2019), those are considered legally possessed.

What You CANNOT Legally Do

🚩 Buy Large-Capacity Magazines in CA

No store in California can sell you a magazine over 10 rounds.

🚩 Import Them

You cannot legally bring large-capacity magazines into California from other states.

🚩 Manufacture Them

You cannot make your own magazines over 10 rounds.

🚩 Sell or Transfer Them

You cannot give, lend, or sell large-capacity magazines to anyone else in CA.

🚩 Use Them at Most Ranges

Most public ranges prohibit magazines over 10 rounds, regardless of possession legality.

CA-Compliant Magazine Options

Since you can't buy standard-capacity magazines, here are your legal options:

1. Factory 10-Round Magazines

Manufacturers make 10-round versions specifically for CA:

Glock 10-rounders
PMAG 10s
Smith & Wesson 10s

Pros: Legal, reliable, easy to find Cons: Only 10 rounds (obviously)

2. PMAG 10/30 (and similar)

These look like 30-round magazines but are permanently blocked to 10:

PMAG 10/30 (Magpul)
Hexmag 10/30
Various other "10/30" conversions

Pros: Look normal, fit in standard mag pouches Cons: Still only 10 rounds, cost more than 10-rounders

3. Permanently Blocked/Pinned Magazines

Standard magazines that have been professionally blocked:

Must be "permanent" (riveted, epoxied, welded)
Cannot be easily reversed
Many gun stores offer this service

Cost: Usually $10-20 per magazine Pros: Can use standard magazine bodies Cons: Permanent modification

4. "CompMag" Fixed Magazine

A special magazine that locks into place:

Holds 10 rounds
Cannot be removed without disassembling rifle
Top-loading only

Pros: Quick reloads (compared to featureless) Cons: Fixed to one rifle, expensive (~$65)

Using Magazines at Shooting Ranges

Most CA Ranges Require:

10-round maximum
Magazines must be legal (no grandfathered 30s at most ranges)
Some allow "freedom week" magazines with proof

Always call ahead and ask their specific policy.

Frequently Asked Questions

Q: Can I keep magazines I owned before 2000?

A: Yes, those are grandfathered and legally possessed.

Q: What about "Freedom Week" magazines?

A: If you acquired magazines during March 29-April 5, 2019, those are considered legally possessed. Keep proof of purchase if possible.

Q: Can I travel out of state, buy magazines, and bring them back?

A: No. Importing magazines into CA is illegal, even if legally purchased elsewhere.

Q: What if I move to California with magazines?

A: If you legally owned them in another state before moving, you can bring them. There's no "registration" requirement for magazines.

Q: Can I modify a 30-round magazine to hold 10?

A: Yes, but the modification must be "permanent." Simply inserting a block that can be removed is not sufficient.

Q: Do rimfire magazines (like for 10/22) have the same restrictions?

A: Yes, rimfire magazines over 10 rounds are treated the same as centerfire.

Q: What about "magazine rebuild kits"?

A: These exist in a legal gray area. Selling "repair parts" is technically legal, but if assembled into a magazine over 10 rounds, that magazine is illegal.

Q: Can I lend my 10/30 magazines to a friend?

A: Yes, 10/30s that are permanently blocked to 10 rounds are legal to lend/sell.

Practical Tips for CA Gun Owners

At the Range:

Bring multiple 10-round magazines (5-10 is good)
Label your magazines (Sharpie works)
Have a mag pouch/carrier
Practice magazine changes - 10 rounds goes fast

For Competition:

Most CA matches allow 10-round magazines only
Practice your reloads - they're part of the sport now

For Home Defense:

10 rounds is still plenty for most defensive situations
Focus on shot placement over capacity
Have spare magazines accessible

The Future of CA Magazine Laws

The magazine capacity ban is being actively litigated:

Duncan v. Bonta may reach the Supreme Court
If SCOTUS takes the case, the ban could be struck down
Or the 9th Circuit ruling could stand

Stay informed through CRPA and FPC for updates.

Conclusion

California's magazine laws are:

Confusing (even lawyers disagree on details)
Constantly changing (court cases ongoing)
Strictly enforced (for sales/transfers)

Your safest bet: Use factory 10-round magazines or permanently blocked 10/30s. They're legal, available everywhere, and you won't have to worry. Remember: Even with 10-round magazines, you can still be an effective shooter. Focus on fundamentals, not capacity.
