The end of this story goes like this. After seeing the hoops one must jump through, the limited options, and increased cost, I have decided that the switch to left is not for me. I have shot lefty with right handed guns all my life, and have done just fine. I will continue to do so. I thought the 870 Express with the addition of a slug barrel would be a good set-up that would be versatile and not cost a fortune to switch hit with. Thanks to everyone for your help and information. Peace.
