I have this added to a shotgun post but it will probably be better here. So I'm looking at a used Remington 870 at a local shop. They say it is a "Police Magnum" but the receiver only says "870 Magnum." It is an older gun but I'm not sure the year, it has those white plastic spacers on the stock if that helps. Did the Police model ever not say "Police" on them? If they didn't how can I tell if it is a Police? By the way I am a bit skeptical because it has nice glossy wood and a deep blued finish.
