Isn't the 22/45 a fiberglass reinforced poly? I believe it's Dupont Zytel, more a nylon resin than plastic or polymer. I know those are very good base guns. The Zytel is firmer than polymer and is a strong foundation for the barrel and action. Nothing there rides on rails.
I was thinking more along the lines of the polymer Walther P22, which is from what I can see mostly a plinker.
