Born and raised in MN. Currently live in Illinois which not gonna lie, kind of sucks but I've got a good job and wife's family is around so that makes up for it
Anyways, MN has had on and off bill attempts for gun regulation since I was a kid and none ever get anywhere. I wouldn't be worried about a bill introduction. It'll most likely end up in the pile with the rest. People need to mostly ignore bill introductions as anyone can introduce one for any stupid reason, and they only begin to have a chance of passing the house and senate if they make it out of committee which none of these are like to. If one does, then it's the time to matter.
St. Paul passed a local ordinance regarding assault weapons, but Minnesota has state laws that prevent local gun bans so it's being thrown out by the courts just taking time like courts do.
