They had them at Vance's in Columbus. Piles of them, long gone now though. I think Vance's in Columbus and Kiesler's in Indiana buy most of them in this area, then they sometimes sell them in their stores and sometimes elsewhere. Good luck.

If you can find an older 870 express I would put on these http://xssights.com/index.php?nID=sights&cID=Sights&pID=sights&sID=shotgun

Their customer service with me recently was great.

Of course Vang Comp is pretty awesome too. https://vangcomp.com/gun_accessories.html

I had a Benelli Nova once and could not get over the fat, toy feeling reciver.
