Connecticut State Law says:
Sec. 29-35. Carrying of pistol or revolver without permit prohibited. Exceptions. (a) No person shall carry any pistol or revolver upon his or her person, except when such person is within the dwelling house or place of business of such person, without a permit to carry the same issued as provided in section 29-28. The provisions of this subsection shall not apply to the carrying of any pistol or revolver by any parole officer or peace officer of this state, or parole officer or peace officer of any other state while engaged in the pursuit of official duties, or federal marshal or federal law enforcement agent, or to any member of the armed forces of the United States, as defined in section 27-103, or of this state, as defined in section 27-2, when on duty or going to or from duty, or to any member of any military organization when on parade or when going to or from any place of assembly, or to the transportation of pistols or revolvers as merchandise, or to any person transporting any pistol or revolver while contained in the package in which it was originally wrapped at the time of sale and while transporting the same from the place of sale to the purchaser's residence or place of business, or to any person removing such person's household goods or effects from one place to another, or to any person while transporting any such pistol or revolver from such person's place of residence or business to a place or individual where or by whom such pistol or revolver is to be repaired or while returning to such person's place of residence or business after the same has been repaired, or to any person transporting a pistol or revolver in or through the state for the purpose of taking part in competitions, taking part in formal pistol or revolver training, repairing such pistol or revolver or attending any meeting or exhibition of an organized collectors' group if such person is a bona fide resident of the United States and is permitted to possess and carry a pistol or revolver in the state or subdivision of the United States in which such person resides, or to any person transporting a pistol or revolver to and from a testing range at the request of the issuing authority, or to any person transporting an antique pistol or revolver, as defined in section 29-33. For the purposes of this subsection, "formal pistol or revolver training" means pistol or revolver training at a locally approved or permitted firing range or training facility, and "transporting a pistol or revolver" means transporting a pistol or revolver that is unloaded and, if such pistol or revolver is being transported in a motor vehicle, is not readily accessible or directly accessible from the passenger compartment of the vehicle or, if such pistol or revolver is being transported in a motor vehicle that does not have a compartment separate from the passenger compartment, such pistol or revolver shall be contained in a locked container other than the glove compartment or console. Nothing in this section shall be construed to prohibit the carrying of a pistol or revolver during formal pistol or revolver training or repair.
(b) The holder of a permit issued pursuant to section 29-28 shall carry such permit upon one's person while carrying such pistol or revolver.
AND
Sec. 53a-181. Breach of the peace in the second degree: Class B misdemeanor.

Notice..., Conneticut Law 53a-181(6) says: '...Creates a Hazardous/Physically Offensive Condidtion in Public [i.e. Open Carry of a Loaded Pistol] by... a Person NOT Licensed or Priviledged to do so.
Open Carry of a Loaded Pistol, is, thus to me, especially with a Pistol Permit under Conneticut Law 29-28, Lawfull as exempt per the terms of 53a-181(6), by its own Penal terms.
