From Star-Tribune:

Also called “suppression devices,” the metal tubes that enable guns to fire more quietly are one step closer to becoming legal after the House Public Safety and Crime Prevention Committee voted Thursday evening to pass a measure legalizing them.

It heads next to the House floor for a vote, but it’s uncertain whether gun-related legislation will gain traction in the Senate, while Gov.Mark Dayton said he has no interest in changing the state’s existing gun laws.

The committee also cleared measures allowing permit holders to carry guns on State Capitol grounds without first notifying the state Department of Public Safety and easing the purchase of guns in other states.
