Despite this fact, a person with a CPL who is actively carrying a concealed firearm "on or about his person" still has a duty to inform the officer of his CPL status and the location of his firearm.
In counties where the local Gun Board delivers questionable service, it is not uncommon for law enforcement officers on a traffic stop to inform the driver that he was issued a CPL.
The key thing to know about visiting other reciprocal states with your concealed firearm is that the laws are probably different than Michigan's. So before you go, jump on the Internet and do your research. Ignorance of the law is no excuse for running afoul of it.
Do keep in mind, however, that private property rights over-rule a CPL-holder's right to Open Carry in a state of Michigan enumerated Pistol-Free Zone. Thus, the owner of a bar or a church, for example, can tell you to take a hike if they object to your openly carried handgun.
Instead the buyer can just go to either a gun dealer or find a private seller. If the seller is a private party, the buyer would be wise to visit the state of Michigan's web site to download a Michigan Pistol Sales Record Form to lawfully document the transfer of ownership of the handgun. Additionally, the buyer has to complete the process by having his pistol purchase documented with his local law enforcement within five days.
