I'm holding a friend's guns, he's gonna be out of the country for a while, and one of them is a relatively new Express. This has been little used, mostly on snow geese.
I took it apart to compare with the 870s I have and noted that:
First, I'm no smith, but taking those dimples out would require little besides a drill and some time.
Second, the new plastic spring retainer in the end of the mag tube is another POC.So's the mag follower.
Third, I took it all the way down and gave it a cleaning. I see now what folks have been saying about grunge buildup. A good scrub, wipedown and relube worked wonders for smoothness and an action that even sounded slick.
Fourth, metallic trigger group, but it seems different than the older ones I have. The trigger was, to be charitable, heavier than normal. I'd guess 8 lbs or so.
All in all, it's a good shotgun kept from being a great shotgun by some cost/corner cutting and attention to the bottom line instead of to quality....
