buckeyejim; Was reading your post and noticed that your 870 20 gauge is a LW model. I have a 870 LW 20 gauge that is a early model that is 28" 2 3/4 inch chamber, fixed full choke. It has the small magazine ring that a quarter won't fit throught. I know the newer barrels won't fit mine because they have a larger magazine ring. I was wondering if your 870 came from the factory with the small ring? Is yours an early model? I have been told that if the serial number ends with a "K" it will eject a 3" shell. Mine does end with a "K" but I can not find a barrel with a 3" chamber with small magazine ring. You might have a hard to find gun. Would you please give me some more information about yours? Mine was also made before screw-in chokes. Many thanks, cluck
