That's an old list, and it's not completely accurate anymore. We've discussed the differences between Police and civilian 870s here before,
this thread specifically goes into details.

Am I right? How the Police is better than a normal 870?
In a nutshell, you get a higher-quality finish with the Police, more inspection and human attention during assembly, and a smoother action out of the box. Other than that, they're the same design, and the major components (barrels, receivers, etc) are manufactured the same way using the same materials. There tend to be differences in features, and some small parts, but that depends on which civilian model you're comparing the Police guns to, and anything that comes on a Police 870 can also be installed on an Express or Wingmaster.
Specialty builders like
AI&P Tactical & (I've been told)
Wilson Combat both build their high-end custom 870s by upgrading and refinishing Expresses, because they know it's the same gun. Odds are Nighthawk does this as well.
