Yesterday I happened to find a You Tube video where a Canadian "off gridder" was recommending a single barrel shot gun as a survival gun. His had a 13" barrel, which he said is perfectly legal in Canada. he discussed a little bit of the Canadian gun laws, talking about pistols and semiautomatic rifles being on the "restricted" list( read prohibited). It struck me that a "sawed off" 13"barreled shotgun that our laws classify the same as a machine gun has not been pointed out by our Canadian friends as being terrible and worthy of their government banning.
