Justipedia explains Deadly Weapon
A deadly weapon is basically an item that can be used to kill. Firearms in particular are considered a very dangerous deadly weapon; and there are both federal and state laws which regulate their use. The concealed carrying of firearms on one's person is especially regulated. For example, states frequently prohibit a person who has committed any felony, or any person who has been committed to a mental institute to treat a mental illness from carrying concealed firearms. This is to try to prevent unnecessary deaths or violent crimes from happening.
