Know the Data.
Know Your Setup.

There’s a lot of noise around magazine capacity. Legislation. Restrictions. Debate.

Before the politics — there’s the data.

And the data tells a clear story.

The Numbers

According to the NSSF Detachable Magazine Report (1990–2021), nearly one billion detachable magazines are in circulation across the United States.

~963M

Total detachable magazines in circulation — pistols + rifles

74%

Hold more than 10 rounds — approximately 717 million units

26%

10 rounds or fewer — approximately 246 million units

Magazine distribution by type (millions)
Pistol 11+ rds
209M
Rifle 11–29 rds
60M
Rifle 30+ rds
448M
All ≤10 rds
246M
Typical handgun magazine capacity by caliber
9mm full/compact
17 rds
.40 S&W
13 rds
.45 ACP
10 rds
.22 LR
10 rds

Rifle magazines with 30+ round capacity alone account for an estimated 448 million units. Pistol magazines over 10 rounds add another 209 million.

The so-called “high capacity” magazine isn’t an outlier.

It’s the standard.

What Your Caliber Actually Ships With

The debate over capacity limits often ignores what manufacturers consider factory standard. Here’s what ships in the box:

Caliber / Platform Typical Capacity Notes
9mm (full/compact) 15–17 rounds Factory standard
9mm (subcompact) 6–10 rounds Prioritizes concealability
.40 S&W ~13 rounds Full size
.45 ACP ~10 rounds Full size
.22 LR ~10 rounds Varies widely
AR-15 / MSR 30 rounds Standard issue from manufacturer

A full-size Glock 17 ships with 17 rounds. An M&P9 ships with 15 to 17. These aren’t extended configurations. That’s stock.

The Legal Landscape — Know It Before You Travel

As of 2026, 14 states plus Washington D.C. restrict magazine capacity. The other 36 states have no restrictions.

State Capacity Limit Applies To
California 10 rounds Handgun & Rifle
Connecticut 10 rounds Handgun & Rifle
Hawaii 10 rounds Handgun only
Maryland 10 rounds Handgun & Rifle
Massachusetts 10 rounds Handgun & Rifle
New Jersey 10 rounds Handgun & Rifle
New York 10 rounds Handgun & Rifle
Rhode Island 10 rounds Handgun & Rifle
Washington 10 rounds Handgun & Rifle
Colorado 15 rounds Handgun & Rifle
Vermont 10 rds rifle / 15 rds handgun Both
Delaware 17 rounds Handgun & Rifle
DC 10 rounds Handgun & Rifle

The federal ban from 1994 to 2004 reduced large-capacity magazine use in crime to around 10%. Once it expired, that number climbed back to 22% by 2010. No federal restriction is currently in effect.

Know the law for every state you carry or travel through.

Why It Matters for Your Setup

If you’re building an armory — not just stacking gear — capacity is part of the equation.

Knowing what’s standard for your platform means you can stage your setup correctly. Store your mags intentionally. Know what you’re running and why.

That’s the difference between a gun wall and an armory.

  • Organized.
  • Intentional.
  • Built with purpose.

HexCore Mounts exist to help you build that.
