US House Panel Approves Law That Will Allow Firearms-Owners To Cross Any State Line With A Hidden Weapon

Get Ready for Concealed Guns in All 50 States

The House Judiciary Committee late Wednesday voted 19-11 for the Concealed Carry Reciprocity Act of 2017, which would amend the federal criminal code to allow the concealed transport of handguns across state lines, so long as both states allow it. States will not be able to impose their individual requirements for a concealed carry license on armed travelers from other states.
