I have a 870 sp from 1987, it has a parkerized finish, better than the matte finish that is used on the express models, the wood is dark stained walnut, and it is better looking than the cheap wood used on the express models. In my opinion it the best 870 pump ever made, except for my vintage wingmaster that was made in the late 50's, and it's as slick snot on glass! If I ever see another special purpose 870 for sale locally, I will buy it in a heartbeat!
