Massachusetts Firearms Charges We Handle

Firearms charges in Massachusetts can carry severe consequences. Many of these offenses are governed under Massachusetts General Laws Chapter 269, which covers crimes against public safety and includes strict penalties for illegal possession, improper storage, and other firearm-related offenses. Below are the primary charges we defend and the legal background behind each.

Illegal Possession of a Firearm

Under M.G.L. c. 269, § 10(a), it is illegal to possess a firearm outside your home or business without a valid License to Carry (LTC). This charge carries serious penalties, including mandatory minimum jail time upon conviction. Even if the firearm is legally owned in another state, Massachusetts law still requires compliance with local licensing regulations. If you’ve been charged with Illegal Possession of a Firearm, our Massachusetts firearms attorneys are ready to assess your case and build a strong defense.

At the Law Office of Matthew W. Peterson, we know how to challenge the legality of searches and arrests related to firearm possession. We understand the importance of every detail in firearm cases and can help protect your rights during investigation and trial. With our deep familiarity with M.G.L. c. 269 and local enforcement trends, we offer practical, strategic guidance. Don’t risk your freedom—let our criminal defense attorneys evaluate the charges and prepare a defense that works for you.

Carrying a Firearm Without a License

Carrying a firearm without an LTC is prosecuted under M.G.L. c. 269, § 10(h) and often involves penalties of up to two and a half years in jail, or more for repeat offenses. This charge applies whether or not the firearm was loaded or used. A valid LTC must be in your possession at the time of the alleged offense. Our aggressive criminal defense attorneys help clients contest such charges through pre-trial motions, negotiations, or trial when necessary.

If you’re facing this charge, our criminal defense law firm brings extensive courtroom experience to defend your rights. We analyze all evidence, from the initial stop to the firearm’s discovery, to ensure your rights were not violated. We understand what it takes to challenge flawed police procedures or improper stops. A conviction can have lifelong consequences—let our firearms attorneys protect your future.

Unlawful Possession of Ammunition

Under M.G.L. c. 269, § 10(h)(1), possessing ammunition without a valid Firearm Identification (FID) card or LTC is a separate criminal offense in Massachusetts. Many people are surprised to learn they can be charged even without having a firearm in their possession. Penalties can include fines and imprisonment. If you’ve been accused, you need a defense attorney who understands the nuances of this law.

We’ve defended clients facing ammunition-related charges and understand how prosecutors build their cases. Our Massachusetts firearms attorneys examine whether law enforcement violated your rights during searches or failed to establish your knowledge of the ammunition. We’re ready to step in and help you defend against these charges.

Possession of a Large Capacity Firearm

This serious charge, governed by M.G.L. c. 269, § 10(m), involves possessing a firearm capable of holding more than ten rounds without the appropriate license. In Massachusetts, a Large Capacity License is required, and the weapon must be lawfully registered. Violations carry enhanced penalties, including potential mandatory minimum sentencing. These cases require a detailed legal approach due to the complex nature of firearm classifications and licensing.

At our criminal defense law firm, we work with experts when needed to challenge the classification of the firearm involved. We also look at whether the firearm was lawfully owned or lawfully stored, and whether any procedural rights were violated during your arrest. If you’ve been charged with this offense, reach out now for a strategy session with our defense attorneys.

Improper Storage of a Firearm

Improper storage of a firearm is charged under M.G.L. c. 140, § 131L, which requires that firearms be stored in a locked container or equipped with a tamper-resistant locking device unless carried or under direct control. A violation of this law, even without any actual use of the firearm, can result in criminal penalties. If the firearm was accessible to minors, the penalties are more severe.

Our team helps clients defend against these charges by challenging evidence, police procedures, and the definition of “proper storage” in each unique context. Whether in your home, vehicle, or place of business, our criminal defense attorneys investigate every aspect of the case. We are committed to protecting your rights while navigating this strict area of Massachusetts firearms law.

Firearms Legal Services We Offer

In addition to defending criminal charges, the Law Office of Matthew W. Peterson is also a trusted Massachusetts gun rights attorney. Our services extend beyond courtroom representation to help you maintain or restore your legal rights related to firearm ownership.

LTC Applications

Obtaining a License to Carry (LTC) in Massachusetts is a highly regulated process governed by M.G.L. c. 140, § 131. Even minor issues in your background or documentation can result in delays or denials. As experienced firearms attorneys, we guide clients through the application process, ensuring all legal requirements are met and that your submission is clear, complete, and fully compliant.

If necessary, we can also assist in preparing supporting documentation and legal justifications to strengthen your application. Our goal is to position you for a successful outcome and help you legally exercise your Second Amendment rights in Massachusetts.

Non-Resident Temporary LTC

Massachusetts also offers a Temporary Non-Resident License to Carry Firearms under M.G.L. c. 140, § 131F. This license allows non-residents to carry firearms while visiting the state, but the application process can be complex and highly discretionary. Applicants must submit forms through the Massachusetts Firearms Records Bureau and meet strict criteria.

Our criminal defense law firm helps non-resident clients complete the application correctly, respond to any follow-up inquiries, and ensure all legal standards are met. We work to minimize complications and improve the likelihood of approval for lawful visitors who require a temporary LTC.

Appealing Firearm License Denials

If your firearm license has been denied or suspended, you have the right to appeal under M.G.L. c. 140, § 131(f). Our law firm has extensive experience representing individuals in these appeals, working to reverse unjust decisions by police chiefs or licensing authorities. We prepare all necessary evidence, including affidavits, hearings, and expert testimony, to support your case.

Restoration of Gun Rights Following a Conviction

Having a criminal conviction can disqualify you from possessing firearms in Massachusetts. However, certain individuals may qualify for relief under the law. The Law Office of Matthew W. Peterson assists clients in petitioning for the restoration of their rights, following strict legal standards and timelines.
