Q: A former student of mine recently contacted the Attorney General’s office to ask whether he and his wife (each has a valid CCW permit) could legally carry each other’s firearms. Could you please shed some light on this? This question has been asked and addressed on the MCRGO Forums web site but not by an attorney. Perhaps this would be a good question for the MCRGO newsletter.
A: This is a good question that comes up repeatedly. Like most good questions, it does not have an easy answer. The reason a person cannot normally possess a pistol unless it is registered to them is MCL 28.422 which states, “Except as provided in subsection (2), a person shall not purchase, carry, or transport a pistol in this state without first having obtained a license for the pistol as prescribed in this section.” HOWEVER, MCL 28.422a exempts CPL holders from the requirements of MCL 28.422. The CPL is what lets you have a pistol that is licensed to someone else. Therefore, a person with a CPL may legally have a pistol for which that the person has not personally obtained the license to purchase. But there’s a complication, “safety inspection” is Michigan’s version of registration. MCL 28.429 states, “A person within the state who owns or comes into possession of a pistol shall ... present the pistol for safety inspection.” While MCL 28.429 does not give a time within which the safety inspection must occur, the law would presume a reasonable time. I believe that you could take someone else’s weapon to the range and then return it, but if you intend to use it for any length of time, you should present it for safety inspection. While unusual, I see nothing in the law that forbids more than one ‘safety inspection,’ or successive safety inspections by different people. Probably, the police will refuse to do a safety inspection in a situation like this, because it is unusual. If they do, make a note of the date and officer. Then, you would have a good defense if you were charged with “Failure to Present a Pistol for Safety Inspection
