Restricted: Illinois bans possessing, buying or selling magazines that hold more than 15 rounds for handguns or more than 10 rounds for long guns.
Illinois bans possessing, buying or selling magazines that hold more than 15 rounds for handguns or more than 10 rounds for long guns. Magazines owned before January 10, 2023 may be kept only on private property you control or that is closed to the public with permission, at a licensed range or competition, at a dealer or gunsmith for repair, or while traveling to or from those places unloaded and in a case. The law lists no exemption for visitors. A violation is a petty offense with a $1,000 fine. A federal appeals court reversed an order blocking the law in July 2026; appeals may continue. Assume both limits apply.

- IndianaPermitted
Indiana sets no state limit on magazine capacity — there is no cap on how many rounds a magazine can hold. Indiana's prohibited-weapons chapter (IC 35-47-5) restricts machine guns and armor-piercing handgun ammunition but sets no magazine-capacity limit, and IC 35-47-11.1 bars local governments from regulating firearms, ammunition or firearm accessories — so no local limit applies either.

- IowaPermitted
Iowa sets no state limit on magazine capacity — there is no cap on how many rounds a magazine can hold. Iowa Code chapter 724 (Weapons) contains no magazine-capacity restriction, and section 724.28 bars cities, counties and townships from regulating firearms or "firearms attachments" that are lawful under state law — so no local limit applies either.
