When Does Illegal Firearm Possession Become a Federal Crime?

 Posted on March 21, 2026 in Criminal Defense

Not every weapons charge stays in state court. When certain factors are present, a weapons charge can be picked up by federal prosecutors, and the difference in consequences is significant.

Under 18 U.S.C. § 922, federal law prohibits certain people from possessing firearms and sets strict rules about how guns can be bought, sold, and transferred. Violations of this statute are prosecuted in federal court and carry penalties that are often harsh.

If you or someone you love is facing a weapons charge in 2026, Worcester County, MD weapons crime defense lawyers can help you understand whether federal charges are a possibility and what can be done to fight them.

What Makes a Gun Charge Federal Instead of State?

Most gun charges are handled at the state level. However, certain factors can push a case into federal court. These include:

• A prior felony conviction with a firearm found in possession

• A firearm that crossed state lines or is connected to interstate commerce

• A prohibited person under federal law, such as someone with a domestic violence conviction or an active restraining order

• A gun that was used in connection with a drug trafficking offense

• An illegally modified firearm, such as a converted automatic weapon or an unregistered short-barreled rifle

• A stolen firearm or one with a removed or altered serial number

When federal prosecutors get involved, the full weight of the U.S. government is behind the case. That is a very different situation from a state prosecution.

What Does Maryland Law Say About Illegal Firearm Possession?

At the state level, Maryland Criminal Law § 4-203 prohibits wearing, carrying, or transporting a handgun without a permit. This applies whether the handgun is concealed or openly carried. A first offense is a misdemeanor, but it can still result in jail time and fines.

Maryland also has its own set of prohibited persons rules. People with prior felony convictions, certain misdemeanor convictions, and those with a history of mental illness are prohibited from possessing firearms under state law. When a person falls into one of these categories and is found with a gun, the case can be prosecuted at both the state and federal levels at the same time.

What Are the Federal Penalties for Illegal Gun Possession?

A conviction for being in felony possession of a firearm under 18 U.S.C. § 922(g) can result in up to 10 years in federal prison. If the charge is connected to a drug trafficking offense, the penalties increase significantly. Using a firearm during a drug crime or violent crime carries a mandatory minimum of five years, which must be served on top of any other sentence.

Federal sentences are served in federal prison, and federal inmates are required to serve at least 85 percent of their sentence before becoming eligible for release. There is no parole in the federal system. Understanding the full weight of what you are facing is one of the most important reasons to get legal help immediately.

What Are the Possible Defenses to a Federal Gun Charge?

Federal gun cases are complex, but there are real defenses available, including:

• Challenging whether the search that uncovered the firearm was lawful under the Fourth Amendment

• Arguing that the defendant did not knowingly possess the weapon

• Challenging whether the firearm meets the federal definition of a regulated weapon

• Questioning whether the government can prove all the elements of the charge beyond a reasonable doubt

In some cases, the way evidence was gathered or stored can also be challenged. An attorney with federal court experience knows how to navigate these cases and where the prosecution's evidence is most likely to fall short.
