On the issue of legalizing suppressors in Minnesota; Looks like things may not be going so smoothly in the conference committee per the email I received from MN-GOCRA.
Please contact Speaker of the House Kurt Daudt and Senate Majority Leader Tom Bakk. GOCRA has stated that both these guys are pro 2A but are being pressured by other policy members.

contact info for Bakk and Daudt, respectively.
