Statute-cited, last verified 2026-07-31

Status: Restricted
Effective: 1992-07-01
Verified: 2026-07-31

Restricted

Yes. The 10-round limit reaches any detachable magazine designed for or capable of use with a pistol; magazines with no pistol application are unrestricted. Limit: 10 rounds. Effective 1992-07-01.

Controlling law: Haw. Rev. Stat. § 134-8(c)

Contested entry

Litigation Status and Details

Not strictly handgun-only: because the test is 'designed for or capable of use with a pistol,' AR-pattern rifle magazines usable in AR pistols fall within it. Possession while inserted in a pistol is a class C felony. Hawaii has no separate rifle-magazine cap.

The statute in practice

Hawaii Law in Detail

Hawaii Revised Statutes section 134-8(c) is keyed to a magazine's design or capability for use with a pistol, not to the firearm in which the owner plans to use it. A detachable rifle magazine that also functions in a pistol can therefore fall within the statutory text.

The same subsection distinguishes ordinary possession from possession while the device is inserted into a pistol, which carries the statute's higher class C felony penalty.

What it means for you

Practical Notes

Confirm the manufacturer's stated compatible firearms rather than relying only on the product label or the buyer's intended host. Shared-pattern magazines, especially AR-pattern devices, require a pistol-compatibility check.
