I'm OK with Ruger putting cheap plastic panels on the Wrangler. It's built to the lowest possible price point and I already had a bunch of old wood panels knocking around to choose from. And even if they did put a set of wood laminate panels on it I may prefer something else anyway. I feel the same way about the standard blued revolvers and their "hard rubber" panels (which look and feel like plastic to me). They may look more correct like the hard rubber panels on the 19th century SAA but I end up changing them out to something else.
A few dollars here, a few dollars there and the Wrangler becomes a Single Six. We should be thankful they decided to offer three colors otherwise it would have been the Model T of single actions.
