Been looking for the right ones for a long time. Picked up the 12 locally and finally found the 20 in Dallas. I have something of an affinity for 870s, and the Wingmasters are as nice as they come.
Those 870 Wingmasters are beautiful and the actions are as slick as if they were made of glass! The wood has the no longer used "bowling pin" hard finish and the esthetics of engraving and checkering are as good as it gets! You have something worthwhile, there! That's the sweet stuff!
My brother got a 20ga Wingmaster like yours but with the vented rib when one of my grandpas died. The one we learned to dove hunt with. Still jealous, lol
