I'm voting on the wood. Never got into the tupperware stocks, although I do have a couple.
Yeah, my Mossberg 590 sports black plastic wares, but it's strictly for my police duties.
My HD scattergun is my Cimarron 1878 SxS 12 gauge coach gun. The next shotgun I buy will be either a Remington 870 or a Winchester 1300. And yes, they will both (whichever one I pick) be wearing wood.
