What is a Weapons Offense in Colorado?

There are many of types of weapons that are potentially illegal in the state, either by virtue of the nature of the weapon itself, or by the circumstances under which it is possessed or used. Here are some of the criminal laws regarding weapons in Colorado:

An “illegal weapon” includes a blackjack, brass knuckles, a switchblade, a gravity knife or a gas gun. Possession of a dangerous weapon is a class 5 felony. Possession of an illegal weapon is a class 1 misdemeanor.
  • Defaced Firearms (CRS 18-12-103). It is a class 1 misdemeanor to possess a firearm, knowing that the manufacturer’s serial number has been removed or altered.
  • Concealed Weapons (CRS 18-12-105). Carrying a concealed knife or firearm is a class 2 misdemeanor. Carrying or bringing a firearm or an explosive or similar device into any building housing the general assembly or where any legislative hearing or meeting is conducted, or where any member or employee of the general assembly is located, is likewise a class 2 misdemeanor.
  • Carrying a Weapon on School Grounds (CRS 18-12-105.5). This is a class 6 felony. It applies to any deadly weapon possessed or carried onto the property of any school. This includes not only public schools, but also private schools, universities, vocational schools and seminaries.

  • Previous Offenders (CRS 18-12-107). Possession or use of a weapon by a person who has a prior felony conviction (or for attempt or conspiracy to commit a felony) is a class 6 felony. If the prior felony conviction was for burglary or arson, or if it involved force or the threat of force, possession or use of a weapon within 10 years is a class 5 felony.
  • Juveniles (CRS 18-12-108.5). Possession of a handgun by a person under the age of 18 is a class 2 misdemeanor. For a second offense, it is a class 5 felony.
