MN allows open carry.
it’s the MPPA (Minnesota Personal Protection Act)
MANY states allow open carry. Once upon a time, open carry was considered typical public behavior, and concealed carry was considered criminal (gives the concealed carrier an unfair advantage). Thus open carry was legal, and CCW rendered illegal.
Now CCW is becoming the norm, and open carry, even if legal, is objected to, even by some gun owners......."it might frighten the natives"
