ADFD, Welcome! I own both the 870 Wingmaster and the 870 Express. They share many (most) parts in common. The finish on the barrels/receivers are one major difference. The Wingmaster line is blued for a more premium look, while the Express line has a non-reflective black matte finish. The matte finish doesn't look as nice, but it's much more durable. I reload my own trap loads and my hulls are about the dirtiest you've ever seen. There just isn't a problem with ejecting these hulls from either shotgun, so I wouldn't consider ease of ejection as part of your purchasing criteria. Wayne
