Understanding Firearms Charges in New Hampshire

New Hampshire has specific laws related to the possession, use, and transportation of firearms. These laws are detailed in Title LXII of the New Hampshire Revised Statutes Annotated (RSA), particularly in chapters like RSA 159. If you’re facing charges related to firearms, it’s important to understand what those charges mean and what potential penalties you might face.

Some of the most common firearms-related offenses include:

Unlawful Possession of a Firearm

This charge can arise if someone is prohibited from owning a firearm due to a prior felony conviction or court order and is found in possession of one. In New Hampshire, this is governed under RSA 159:3. Being convicted of this offense can result in a felony record and significant penalties, including jail time.

Carrying a Concealed Weapon Without Authorization

Although New Hampshire is a permitless carry state, carrying a loaded pistol or revolver in certain restricted areas or without meeting legal criteria may still lead to charges. This is governed under RSA 159:4, and the specific circumstances of your case will determine whether this results in a misdemeanor or felony.

Possession or Use of Prohibited Weapons

New Hampshire law restricts certain weapons such as blackjacks, slung shots, metallic knuckles, and similar devices under RSA 159:16. Even if the weapon wasn’t used or displayed, possession alone can lead to criminal penalties.
