Exiting a vehicle with a firearm is only allowed to place the firearm in the trunk of the vehicle, unless written permission has been received. ∗∗∗ In 2015, this notification became automatic with the issuance of a permit.

Minnesota is a "shall issue" state for Permit(s) to Carry a Pistol openly or concealed. Some counties have adopted Second Amendment sanctuary resolutions. Sales

Private sales 
There are private seller regulations in Minnesota (Read here: https://www.revisor.mn.gov/statutes/?id=624.7132#stat.624.7132). Private sales do require a background check as per MN 624.7132. The referenced Star Tribune article is not current or is in error. A private seller is guilty of a gross misdemeanor if a private transfer is made to a prohibited person, who can be reasonably suspected as a prohibited person, who then uses or possesses the firearm during the commission of a felony crime of violence within one year of the transfer. Minn. Stat. §§ 609.66, subd. 1f and 624.7132, subd. 12(1)

Gun shows 
All federally licensed firearms dealers must perform background checks at gun shows. All private sales within the state are subject to MN statute 624.7132 regardless of venue. References
