Michigan sets no general limit on firearm magazine capacity. You can legally own, buy, and use magazines of any size for home defense, target shooting, or everyday possession, and no permit or registration is required for the magazine itself. The only real exceptions are narrow: specific caps apply while hunting, and state-owned shooting ranges have their own loading rules. A bill introduced in 2026 would change the general rule, but it has not become law.
What Michigan Law Actually Says About Magazines
Michigan’s firearms statutes focus on who may possess firearms, how to obtain a concealed pistol license, and which specific weapons are prohibited. None of them address magazine capacity for civilian possession. The official compilation of Michigan firearms laws, current through the April 2025 session, contains no definition of “high-capacity magazine” and no section limiting the number of rounds a feeding device can hold.1Michigan Legislature. Firearms Laws of Michigan The prohibited-weapons statute covers automatic firearms, suppressors, and short-barreled weapons, and says nothing about magazine size.2Michigan Legislature. Michigan Compiled Laws 750.224 – Weapons, Manufacture, Sale, or Possession
Federal law is similarly silent. The 1994 federal assault weapons ban capped magazines at ten rounds, but it expired in September 2004 and has not been renewed. So standard-capacity AR-15 magazines, 30-round rifle magazines, and larger drums are all legal to own in Michigan.
Hunting Is Where Capacity Rules Kick In
Hunting is the one everyday activity where Michigan enforces magazine limits, and the rules trip up people who assume their general-possession freedom carries into the field.
Under the Department of Natural Resources’ Wildlife Conservation Order, it is illegal to hunt with a semi-automatic rifle or semi-automatic shotgun capable of holding more than six shells in the barrel and magazine combined. The only exception is .22 caliber rimfire firearms. In practice, a semi-auto rifle holding six in the magazine plus one in the chamber already exceeds the cap, so hunters typically need a reduced-capacity magazine or a magazine limiter.
Migratory bird hunters face a stricter federal rule on top of this. It is illegal to hunt ducks, geese, woodcock, or other migratory species with a shotgun capable of holding more than three shells total, unless the gun is plugged with a one-piece filler that cannot be removed without disassembling the firearm.3eCFR. 50 CFR 20.21 – What Hunting Methods Are Illegal Narrow exceptions exist for certain light-goose-only and Canada-goose-only seasons when other waterfowl seasons are closed.
The Limited Firearm Zone Handgun Rule
Michigan’s Limited Firearm Zone covers the southern portion of the Lower Peninsula, roughly south of a line running from the Lake Michigan shoreline near M-46 east to Saginaw Bay. During firearm deer season in this zone, hunters are restricted to shotguns, muzzleloaders, straight-walled cartridge rifles of .35 caliber or larger, handguns, crossbows, and bows. Standard bottleneck rifle cartridges are not permitted.4Michigan Department of Natural Resources. 2025 Deer Hunting Regulations Summary
A specific handgun capacity rule applies here. A conventional handgun of .35 caliber or larger loaded with straight-walled cartridges may not exceed nine rounds in the barrel and magazine combined. This nine-round cap is separate from the six-round rule on semi-automatic rifles and shotguns and only applies within the Limited Firearm Zone during firearm deer season.
Penalties for a Hunting Magazine Violation
A capacity violation while hunting is a misdemeanor, with the specific penalty tied to what you were hunting. Under MCL 324.40118, a general hunting infraction with no specific species involved carries up to 90 days in jail and a fine between $50 and $500, plus prosecution costs. A deer, bear, or wild turkey violation jumps to a mandatory fine between $200 and $1,000, and a waterfowl violation runs $250 to $500 with a flat $500 fine on a second offense. Elk and moose violations carry significantly higher jail time and fines.5Michigan Legislature. Michigan Compiled Laws 324.40118 – Violation as Misdemeanor, Penalty Conservation officers routinely check magazines and shotgun plugs in the field, and a conviction can also lead to revocation of DNR-issued hunting permits.
Loading Limits at DNR Shooting Ranges
State-owned shooting ranges run by the DNR follow their own administrative rules, and these are stricter than what you can do on private property. By default, you may not discharge a firearm containing more than one round at a time unless the department has posted otherwise or granted written permission.6Michigan Office of Administrative Rules. Michigan Administrative Code – Shooting Ranges on State-Owned Lands Shotguns at ranges equipped with skeet or trap equipment are exempt from this default.
So owning a 30-round magazine is legal, but loading it fully at a DNR range without checking the posted rules puts you in violation of the administrative code. Individual ranges may post higher loading limits for specific activities, so read the signage at the entrance before loading. Range officers can evict anyone engaged in prohibited acts.
Cities and Counties Can’t Add Their Own Limits
You do not need to track different rules in different Michigan municipalities. MCL 123.1102 bars any local unit of government from enacting or enforcing ordinances related to the ownership, purchase, sale, transportation, or possession of firearms or their components.7Michigan Legislature. Michigan Compiled Laws 123.1102 – Regulation of Pistols, Other Firearms, Pneumatic Guns, or Ammunition Magazines are firearm components, so no city, village, or township can ban or restrict them. The Michigan Supreme Court applied this preemption in Michigan Coalition for Responsible Gun Owners v. City of Ferndale (2012), striking down a city ordinance banning firearms in parks. Any local attempt to cap magazine size would face the same barrier.
Pending Legislation Could Change the General Rule
Michigan lawmakers have introduced magazine restrictions in past sessions without success. The most recent effort is Senate Bill 851, introduced on March 18, 2026, by Senator Jeremy Moss, which would add a new section to the Michigan Penal Code prohibiting the sale, production, or possession of high-capacity magazines.8Michigan Legislature. Senate Bill 851 of 2026 The bill was referred to the Committee on Civil Rights, Judiciary, and Public Safety and has not received a hearing. Until a bill like this is signed into law, no capacity restriction applies to general possession.
Crossing State Lines Is a Different Story
Michigan’s permissive rule does not travel with you. Among Michigan’s neighbors, Illinois prohibits high-capacity magazines; Indiana, Ohio, Wisconsin, and Minnesota do not. Drive into Illinois with a standard AR-15 magazine and you could face criminal charges under Illinois law regardless of where you live. Several other states cap magazines at ten or fifteen rounds, so any trip with firearms calls for checking the laws of every state on your route.
Federal law offers limited protection for travel through restrictive states. Under 18 U.S.C. ยง 926A, you may transport a firearm from one place where you legally possess it to another place where you legally possess it, as long as the firearm is unloaded and neither the gun nor ammunition is readily accessible from the passenger compartment.9Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms In vehicles without a separate trunk, the firearm and ammunition must be in a locked container other than the glove compartment or console. This safe-passage rule covers transit; it does not cover extended stops, and it will not help you if your destination itself bans the magazine.
For flights, TSA requires firearms to be unloaded, locked in a hard-sided container, and checked. TSA treats a firearm as loaded if a magazine is inserted, even with an empty chamber, so magazines come out before packing.10Transportation Security Administration. Transporting Firearms and Ammunition TSA rules govern the flight; the law at your destination governs what you do when you land.
