Deadly Weapon Law and Legal Definition
A deadly weapon is generally defined as a firearm or anything manifestly designed, made, or adapted for the purposes of inflicting death or serious physical injury. The term includes, but is not limited to, a pistol, rifle, or shotgun; or a switch-blade knife, gravity knife, stiletto, sword, or dagger; or any billy, black-jack, bludgeon, or metal knuckles.
Use and carrying of deadly weapons are governed by state and federal laws. Generally, use of a deadly weapon in commision of a crime enhances the nature and penalty of the crime. Carrying concealed deadly weapons is governed by state laws, which vary by state. Some states allow licensing of qualified persons to carry a concealed deadly weapon. Because of differences in the laws of the various states, it is possible that a person who is lawfully permitted to possess a deadly weapon in another state may be prohibited from doing under the law of another state. A state permitting licenses to carry a concealed deadly weapon may typically prohibit such a license to the following:
- any person previously convicted of any felony
- any person previously convicted of any misdemeanor involving physical injury to another or domestic violence, unless more than 5 years has elapsed from the date of the conviction
- any person previously convicted of any crime involving the unlawful use, possession or sale of any illegal drug
- any person who has not yet reached his or her 25th birthday who has been previously convicted as a juvenile of a crime which, if committed by an adult, would constitute a felony
- any person who is subject to a Protection From Abuse Order issued by a competent court
- any person who has previously been committed to a hospital or mental institution for treatment for a mental disorder
