Oregon is a very gun friendly state.It is shall issue for ccw (which technically is unconstitutional). The only place you can not carry are federal buoldings and the courthouses. It is better for gun ownership than Texas.
And there is no wave of gun violence in Oregon. These antigun nuts pop up every election.
