In Wisconsin, the penalties for a felon in possession of a firearm start with a Class G felony carrying up to 10 years in prison and a $25,000 fine under state law. Federal prosecutors can charge the same conduct under 18 U.S.C. § 922(g), which since 2022 carries a maximum of 15 years. If you have three or more qualifying prior convictions, the Armed Career Criminal Act sets a 15-year federal mandatory minimum with a maximum of life.
The State Sentence: Class G Felony
Wisconsin Statute 941.29 makes possession of a firearm by a convicted felon a Class G felony.1Wisconsin State Legislature. Wisconsin Code 941.29 – Possession of a Firearm The maximums are 10 years in prison and $25,000 in fines.2Wisconsin State Legislature. Wisconsin Code 939.50 – Classification of Felonies
That 10-year cap is not served as a single stretch of prison time. Under Wisconsin’s bifurcated sentencing structure, the sentence splits into initial confinement of up to 5 years, followed by extended supervision of up to 5 years in the community.3Wisconsin State Legislature. Wisconsin Code 973.01 – Bifurcated Sentence of Imprisonment and Extended Supervision A judge can impose less than the maximum on either side, but the two pieces together cannot exceed the 10-year ceiling.
Judges have wide discretion within those caps. Factors that push sentences toward the top of the range include a lengthy criminal history, whether the firearm was loaded, and whether the defendant was engaged in other criminal activity at the time of arrest. Defendants with prior violent felonies or prior firearms convictions routinely see sentences near the maximum. When more than one charge is filed, judges can stack sentences consecutively rather than have them run at the same time.
Probation is possible instead of prison, but the conditions are strict: mandatory firearm surrender, regular reporting to a probation officer, and restrictions on associating with anyone else who has a felony record. A violation puts you back in front of the sentencing judge with the original prison term available.
What Pushes the Sentence Higher
The Class G felony sentence rarely stands alone. Wisconsin’s dangerous weapon penalty enhancer, Statute 939.63, adds years on top of the maximum sentence for any crime committed while possessing a firearm:4Wisconsin State Legislature. Wisconsin Code 939.63 – Penalties Use of a Dangerous Weapon
- Up to 5 additional years for a felony with a maximum over 5 years or a life term.
- Up to 4 additional years for a felony with a maximum over 2 years but not more than 5.
- Up to 3 additional years for other felonies.
- Up to 6 additional months for a misdemeanor.
The result is that a felon caught with a gun during an armed robbery or aggravated battery faces the 941.29 charge, the underlying violent felony, and the weapon enhancer stacked together. This is where exposure climbs well past what the Class G felony alone would produce.
Certain characteristics of the firearm itself add charges. Stolen weapons often bring separate theft counts. An obliterated or altered serial number creates additional exposure under both state and federal law. Prosecutors read these facts as signs of deeper involvement in criminal activity and charge accordingly.
Federal Prosecution and the Armed Career Criminal Act
The same conduct can be charged federally under 18 U.S.C. § 922(g). Since 2022, the federal maximum for a standard felon-in-possession conviction is 15 years, up from the previous 10-year cap.5Office of the Law Revision Counsel. 18 USC 924 – Penalties
Federal sentences tend to run longer in practice than state sentences for the same conduct. There is no parole in the federal system, and federal sentencing guidelines generally produce more time than Wisconsin state courts impose. Federal prosecutors are more likely to take a case when the defendant has a violent history, when the arrest grew out of a larger investigation, or when drug trafficking is involved.
The Armed Career Criminal Act changes the picture entirely. If you have three or more prior convictions for violent felonies or serious drug offenses, the federal minimum jumps to 15 years with no parole, and the maximum rises to life.5Office of the Law Revision Counsel. 18 USC 924 – Penalties Judges cannot sentence below 15 years once the ACCA applies. The three qualifying convictions do not have to be recent; decades-old offenses still count.
Ammunition and Body Armor: The Federal Gap
Wisconsin’s 941.29 covers firearms only, not ammunition on its own. Federal law does not stop there. Under 18 U.S.C. § 922(g), a convicted felon found with a box of ammunition and no gun still faces up to 15 years in federal prison.5Office of the Law Revision Counsel. 18 USC 924 – Penalties
Body armor is separately restricted. Under 18 U.S.C. § 931, anyone convicted of a federal or state felony that qualifies as a crime of violence cannot purchase, own, or possess body armor. The maximum is three years in federal prison, with higher exposure if the body armor is used in connection with another felony.6United States Sentencing Commission. Amendment 670
What Prosecutors Have to Prove
A conviction under 941.29 requires two elements beyond a reasonable doubt: that the defendant is in a prohibited category (most often through a prior felony), and that the defendant knowingly possessed a firearm.
Prior convictions are usually established with certified court records. When the prior comes from another state or the federal system, prosecutors must show that the underlying conduct would qualify as a felony under Wisconsin law. The label used by the other jurisdiction does not decide the question.7Wisconsin State Legislature. Statutory Felonies in Wisconsin
Possession does not require the gun to be in your hands. Wisconsin recognizes actual possession and constructive possession, where the firearm is in a location you control. A gun in your car, your bedroom closet, or a storage unit rented in your name can support a charge. Courts look at whether you had the ability and intent to exercise control, and they rely on circumstantial evidence like fingerprints, surveillance footage, and witness testimony.
Shared living situations are where this becomes dangerous. If you live with someone who legally owns firearms, the presence of those guns in a location you can access may be enough for prosecutors to argue constructive possession. The safer setup is to have firearms in the home stored in a locked container you have no key or combination for.
The object must also qualify as a firearm. Pellet guns, air rifles, and paintball markers do not meet the definition. A firearm that is broken or partially disassembled can still count if it could be made functional without significant effort, and prosecutors sometimes bring expert testimony on that point. Wisconsin has no antique-weapon exception. Federal law carves out firearms manufactured before 1899; state law does not, and an 1880s revolver in a display case is treated the same as a modern handgun.
Getting Firearm Rights Back
Wisconsin’s ban is for life. The realistic path back is a governor’s pardon. Eligibility requires that at least five years have passed since you completed every part of your sentence, including extended supervision and probation, that you have no pending criminal charges anywhere, and that you are not required to register as a sex offender.8Wisconsin.gov. Pardon Information
The Wisconsin Pardon Advisory Board reviews applications and makes recommendations to the governor, who has sole discretion. The process is selective. A pardon does not erase the conviction, and whether it restores firearm rights depends on the specific terms.
Federal relief is a separate question. 18 U.S.C. § 925(c) authorizes the Attorney General to grant relief from federal firearms disabilities. For decades, Congress blocked funding for this program. The Department of Justice has announced it is developing a web-based application process to accept petitions under Section 925(c), though as of early 2026 the application is not yet live.9U.S. Department of Justice. Federal Firearm Rights Restoration A state pardon that restores firearm rights does not automatically lift the federal prohibition. Relief under both systems may be needed before you can legally possess a firearm again.
