too bad short barrel semi auto's are restricted here in Canada. (any center-fire shotgun or rifle) has to have a 18.5 inch barrel and overall length of around 26 inch minimum or its a restricted fire arm. (mean it goes to the range and back and that is all it can do) but pump action or any other manual action does not have barrel requirements just overall length of 26 inches.
Pretty much the same here in NY.
My semi auto Remington 1100 has a 18" barrel.
