The term " canted" barrel refers to the relationship of the barrel to the frame, hence, whether or not the front sight is set at top dead center (12 o'clock) or "canted" to one side or the other (11 o'clock or 1 o'clock). I don't have a "canted" example handy, but these pics show correct frame/barrel relationship.
The flat on the top of the frame is a little wider than the flat on top of the barrel. If the barrel is "clocked" correctly, there should be equal distance on both sides of the barrel flat in relationship to the frame flat.
Hope this helps
