Texas has no magazine capacity limit. State law does not cap how many rounds a handgun or rifle magazine can hold, and cities and counties are barred from setting their own caps. The only capacity rule that applies anywhere in Texas is a three-shell limit on shotguns used to hunt migratory game birds. Outside that narrow hunting context, magazines of any size are legal to buy, own, and carry.
What Texas Law Actually Says
Texas Penal Code Chapter 46 governs weapons offenses. Nothing in it restricts how many rounds a magazine can hold, for any firearm.1Texas State Law Library. Carry of Firearms – Gun Laws Ten-round, 30-round, 50-round, and 100-round magazines are all legal.
The prohibited weapons list in Section 46.05 covers machine guns, explosive devices, armor-piercing ammunition, and zip guns. Magazines of any capacity are not on it.2State of Texas. Texas Penal Code Section 46.05 Modifying a firearm to accept a larger magazine is not itself a prohibited-weapon offense, so long as the modification doesn’t turn the gun into something separately restricted, such as a machine gun.
The state’s hunting rules confirm the same posture. The Texas Parks and Wildlife Department states there are “no restrictions on the number of shells or cartridges a legal firearm may hold” when hunting game animals or game birds, with migratory birds the sole exception.3Texas Parks & Wildlife Department. Hunting Means and Methods If capacity isn’t capped for deer or turkey, general possession isn’t either.
Federal law doesn’t add a cap. The 1994 federal ban included a 10-round limit on new magazines, but it expired in 2004 and hasn’t been renewed.
Cities and Counties Can’t Add Their Own Limit
Texas Local Government Code Section 229.001 blocks municipalities from adopting or enforcing regulations related to the possession, carrying, ownership, storage, or transportation of firearms, ammunition, or firearm supplies or accessories.4State of Texas. Texas Local Government Code Section 229.001 Magazines sit squarely inside “firearm supplies or accessories.” No Texas city or county can pass an ordinance capping magazine capacity.
The statute has enforcement behind it. Any local ordinance, resolution, or official action that violates the preemption is automatically void, and the Texas Attorney General can seek an injunction against a municipality that tries to enforce one, plus recover costs.4State of Texas. Texas Local Government Code Section 229.001
The practical effect: a magazine that’s legal in rural Texas is equally legal in Houston, Austin, San Antonio, or Dallas. City and county lines don’t change the answer.
The One Exception: Migratory Bird Hunting
The single context where capacity matters legally in Texas is migratory game bird hunting. When hunting doves, ducks, geese, or other migratory birds, a shotgun must be plugged with a one-piece filler so it cannot hold more than three shells total. The rule comes from federal regulation and matching TPWD rules, and the plug has to be impossible to remove without disassembling the gun.5GovInfo. 50 CFR 20.21 – What Hunting Methods Are Illegal
There are narrow exceptions. During certain light-goose-only or early-season Canada goose seasons, when all other waterfowl and crane seasons are closed, the plug requirement is lifted.5GovInfo. 50 CFR 20.21 – What Hunting Methods Are Illegal Specific dates are published in the TPWD Outdoor Annual each year.
For everything else — game animals like deer and turkey, and non-game species like feral hogs and coyotes — no capacity restriction applies.3Texas Parks & Wildlife Department. Hunting Means and Methods A 30-round magazine on a feral hog hunt raises no legal issue.
A migratory bird shotgun violation is a Class C Parks and Wildlife Code misdemeanor, with a fine between $25 and $500, and game wardens can inspect equipment in the field.6State of Texas. Texas Parks and Wildlife Code Section 12.406
Traveling Out of State Changes the Answer
Texas legality doesn’t cross state lines. Roughly a dozen states cap magazine capacity, typically at 10 or 15 rounds, and possession of a larger magazine inside those states can be a criminal offense regardless of where you bought it or where you live. As of early 2026, states with magazine capacity limits include California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maryland, Massachusetts, New Jersey, New York, Rhode Island, Vermont, Virginia, and Washington, with limits ranging from 10 to 20 rounds depending on the state and the type of firearm.
If you’re driving through or flying into one of those states, the fact that your magazine is legal in Texas won’t help you. Check the destination state’s current rules before the trip and either leave restricted magazines at home or transport them in strict compliance with any safe-passage law that applies. In some states the charge is a felony, not a fine.
