Types of Firearm Charges

The Firearm Charges We Defend You Against

When someone has a handgun on their body or inside a vehicle without any proper permit or negligence of transport rules, it becomes chargeable. We conduct independent research and challenge the evidence in the courtroom.

Firearm possession charge for a prohibited person with a prior conviction

Possession by a Prohibited Person

It is illegal for a person with a prior felony conviction, violent crime conviction, or mental health admission to own a gun. We counsel compassionately, research deeply, and fight aggressively in the courtroom to safeguard our client.

Possession of banned weapons such as machine guns and sawed-off shotguns

Possession of Prohibited Weapons

Dangerous items like machine guns, sawed-off shotguns, and some designated assault pistols are banned in Maryland. We strongly fight for our clients and protect their rights through our professional expertise.

Violating Gun-Free Zones

Firearms are prohibited in certain areas like state parks, school property, or near public demonstrations. We analyze the situation, challenge the evidence, and negotiate with the prosecutor to minimize penalties.

Strategies We Practice

The Strategies We Follow to Defend Our Clients

Fourth Amendment suppression of a firearm found in an unlawful search

Fourth Amendment Suppression

If your vehicle or your property was searched without a proper warrant, consent, or probable cause, then the weapon found can be suppressed as illegal evidence.
We challenge the reason behind the police search in the courtroom and apply the Fourth Amendment wherever applicable to suppress the evidence.

Challenging possession of a firearm found in a shared vehicle or common area

Challenging Possession

A gun found in a shared vehicle or common area can be argued about for lack of knowledge or constructive possession. The prosecutors must be able to prove that the person charged was aware of the firearm present and had control over it.
We conduct thorough research and strongly protect our client if he wasn’t aware and didn’t have any control of the firearm.

Testing whether a weapon meets the legal definition of an operable firearm

Testing Weapon Operability

The items should be aligned with the legal definition of a working firearm capable of expelling a projectile. If found otherwise, the weapon can form a basis for the dismissal.
We scrutinize the evidence presented by the prosecutor and challenge the firearm condition in the courtroom.

Our 4-Step Defense Process

From Arrest to Resolution

01

Free Confidential Consultation

We review the charging documents, police report, and your account of events. Immediate bail intervention if you are being held.

02

Independent Investigation

We subpoena dashcams, bodycams, dispatch logs, lab reports, and informant histories. We build our own timeline — not the State's.

03

Pre-Trial Motions & Strategy

Motions to suppress evidence, dismiss for speedy trial violations, and challenge the State's case before it ever reaches a jury.

04

Trial or Strategic Resolution

Aggressive courtroom advocacy when trial is the right move — strategic negotiation, diversion, or PBJ when it protects your future.

cannot say enough good things about my experience with this attorney. From the very beginning, he made sure I understood exactly what was happening, explained all of my options, and broke everything down in a way that made an overwhelming situation much easier to understand. He was patient with all of my questions and made sure I had as much information as I needed to make informed decisions. What stood out to me most, though, was the genuine care he showed me as a person, not just as a client. He made sure I was okay, helped me stay calm during an incredibly stressful time, and even took the time to pray with me. That meant more to me than I can put into words. He was knowledgeable, compassionate, reassuring, and truly advocated for me throughout the entire process. I felt like I had someone in my corner who genuinely cared about both my case and my well-being. I’m incredibly grateful for everything he did for me and would recommend him without hesitation. Five stars truly isn’t enough.

FAQs

Answers to the Most Commonly Asked Questions.

We defend clients charged with illegal possession of a firearm, wearing, carrying, or transporting a handgun, use of a firearm in the commission of a crime, and related offenses. We work by scrutinizing every search for constitutional violations.

The most common client issues include illegal possession of a regulated firearm, wearing, carrying, or transporting a handgun, possession of a firearm by a prohibited person (felon in possession), use of a firearm in a crime of violence, and unlawful storage of a firearm.

Clients fear mandatory minimum sentences, federal prosecution, and the long-term consequences of a firearm conviction on their record, employment, and the right to own firearms in the future.

Illegal handgun possession carries 30 days to 3 years in Maryland, while use of a firearm in a crime of violence carries a 5-year mandatory minimum for a first offense, consecutive to the underlying sentence. Federal charges carry even more severe penalties.

Avoid giving consent for a vehicle or person search and ask for legal counsel. When charged, immediately practice your right to remain silent and do not give statements to the police. If you are lawfully transporting a firearm, understand Maryland's transport laws before you get in the vehicle.

Firearm cases highly depend on the legality of the search. If the police searched you, your car, or your home without proper justification, the firearm may be suppressible as the result of an unconstitutional search. We aggressively litigate Fourth Amendment issues in every firearm case we handle.
