The 870 Police was manufactured on a different production line than the 870 "Express" models. Their receivers were vibra-honed where the "express" models were not. They were parkerized where the "express" models were just painted. They included a tool-steel extractor where the "express" models use an MIM extractor. They also included a heavier sear spring and heavier carrier dog spring. The heavier sear spring reduced the chances of the hammer jumping off the sear from impact and discharging the shotgun. The heavier carrier dog spring helped with reliable feeding and function. The chambers on the police barrels tended to be better polished, reducing the odds you get feed issues from a sticky chamber.
I say "was" because I have no idea what Remington is doing after emerging from the bankruptcy.
The vibra-honed receivers, in general, made for a smoother running action. The parkerized finish holds up to hard wear and abuse better than the paint on the "express" model guns. The Police model guns also don't have those ridiculous dimples in the magazine tube that prevent use of a magazine extension without the need to use a dremel.
Yes. 2 3/4" shells are just fine for defensive purposes.Arent most loads for defensive use 2.75?
An old Wingmaster that's in good shape is a great starting place for a defensive shotgun. A properly made Wingmaster has an action that is slicker than owl snot and they run beautifully. Trouble is that the blued finish isn't usually the best for the kinds of circumstances that the defensive gauge finds itself in. I taught a class yesterday in the rain where the shotguns end up laying on gravel in between shooting exercises...not great for a pretty Wingmaster.My point being they are rare and expensive wouldnt a viable alternative be an older inexpensive Wingmaster With a 2.75” chamber?
I have defensive 870's that started life as a Wingmaster. But my go-to 870 is an "express" gun that I put a rifle-sighted 870P barrel on, had refinished with Cerakote (which has held up very well), replaced the key springs in with 870P springs, and had barrel work done on. It's a great shotgun.
The action on it isn't super smooth, limiting me to .28 splits with it. With a really smooth action on an 870 I can shoot .24 splits. So obviously those extra 4/100ths of a second are going to get me kilt in the streets...but it is noticeable in the feel of the gun.
I bought a lot of 870's during the era of the cheap trade-in 870. And I spent a fair bit of time on Gunbroker picking up various specimens of 870 for $200 a piece. Those days are gone and I doubt they will return.
