Polymer pistols have always been, to me, Law Enforcement and Military oriented. They are lighter and more corrosion resistant for duty use. Given that only those two groups carry pistols in Canada, it doesn't seem that owning one is a need, as most competition pistols are metal, given that target shooting is the only thing private Canadian firearms owners can do with handguns. However, I do own a Walther P99 that I would rather carry over the Brownings and Sigs we have in the work inventory. If you had polymer pistols before and sold them and are now left with metal pistols, that might be your personal yardstick indicating you don't need a polymer pistol as you would have kept one if it was your preference.
