And in addition to whats mentioned above, (my 870P just came in yesterday) if I'm not mistaken about the HD (don't own one, I've only looked at/handled acouple) The 870 Police comes with the high vis follower (not sure about the HD), and the metal trigger group as opposed to the polymer on the HD. You can also get different configurations - barrel lengths, sights, mag capacities, finishes, stocks, etc.,the 870P comes with factory installed sling studs as well. I believe the HD comes only in 18", bead sight, standard capacity, parkerized, w/synthetic stock config.
