Right to keep and bear arms--exception.
Section 23. That the right of every citizen to keep and bear arms in defense of his home, person and property, or when lawfully summoned in aid of the civil power, shall not be questioned; but this shall not justify the wearing of concealed weapons.
Source: Const. of 1875, Art. II, § 17.
(2004) Section does not prohibit the General Assembly from enacting statutes allowing or disallowing the carrying of concealed weapons; the Concealed-Carry Act is therefore constitutional. Brooks v. State, 128 S.W.3d 844 (Mo.banc).
It took an act of the legislature to make that possible. Open Carry by not being prohibited was and is legal in Missouri. Of course in 1985 it became possible (And indeed it happened) that municipal government can prohibit OC within it's municipal limits see Missouri Statute 21.750.3
3. Nothing contained in this section shall prohibit any ordinance of any political subdivision which conforms exactly with any of the provisions of sections 571.010 to 571.070, with appropriate penalty provisions, or which regulates the open carrying of firearms readily capable of lethal use or the discharge of firearms within a jurisdiction, provided such ordinance complies with the provisions of section 252.243.
We would like a modification of this statute.... Stay tuned, something may pop up this week?
