Some states, maybe Kansas?, specifically say resident in their Constitutional Carry laws. Don't think the Maine one does, just typical media reporting. That is to say inaccurate.
Yeah after reading Kansas law summary it really doesn't sound like constitutional carry either Give the AG the option to pick and choose states
Constitutional Carry; SB 45
SB 45
amends laws concerning the concealed carry of firearms. The bill adds language
allowing the concealed carry of a firearm without a concealed carry license issued by the State,
as long as that individual is not prohibited from possessing a firearm under either federal or
state law. The bill specifies the carrying of a concealed handgun cannot be prohibited in any
building unless the building is posted in accordance with rules and regulations adopted by the
Attorney General. Concealed carry licenses will still be issued by the State, but the availability of
those licenses cannot be construed to prohibit the carrying of handguns without a license,
whether carried openly or concealed, loaded or unloaded.
Related to concealed carry licenses, the bill also allows the Attorney General to create a
list of concealed carry handgun licenses or permits from other jurisdictions that have training
requirements greater than or equal to the Kansas requirements. This list can be used by the
Attorney General when reviewing concealed carry license applications and making a
determination about whether an individual has completed an approved handgun safety and
training course required for issuance of a concealed carry license. The bill also defines “equal to
or greater than,” “jurisdiction,” and “license or permit” for the purposes of the new section of law.
The bill amends the definition of “criminal carrying of a weapon” to clarify that it is not
legal for anyone under 21 years of age to carry any pistol, revolver, or other firearm concealed
on one’s person, except when on such person’s land or in such person’s abode or fixed place of
business.
Kansas is constutional carry for residents and non residents (as long as you are not a prohibited person). I contacted the author of the law when they passed it. The only state who restrict con carry to their residents only is wyoming. All others are vermont style full con carry.
