ok, i spent the morning at the local gun show.
i found a remmy 870 express magnum in 20 gauge with a vent rib barrel.
it wears some nice wood stocks, with checkering, has a smooth action and overall in nice shape.
the shell follower is metal and though its a used gun and shows wear on the finish at the mag tube and slide, the slide and bolt are still tight with no slop.
i paid $200 for it. i got an email off to mother remington for a manufacturing date. it feels more solid then the new ones on the racks now.
i'm happy so far
ok, i took the 870 apart. wow did it need to be cleaned ! so i gave it a good cleaning out and then gave it a few drops of oil and cycled a few rounds thru it for a basic functions check and its got a nice smooth action.
i put a new primer in a used shell and fired off a blank and everything works 5x5.
the fire control group is all metal, not sure its steel though, looks like 'die cast or white' metal, but its not plastic
the checkering on the furniture is pressed ( im sure ) and you really cant feel it that much, it looks nice though.
over all its a keeper , for me anyhow, im happy
thanks to all who gave me advice and helped me out.
