Is it possible with some elbow grease and finishing with a parkerizing job to get the express to roughly the same quality as the police model?

I never actually handled the police model but am assuming that it is far superior to the express. I know that the parts will be fitted more precisely and a lot smoother. So would some sanding and polishing to the receiver and other areas yield something close to what you would get with the police model?

If it has been asked before, I did a quick search and found nothing.
 
You'll need a bit more than just parkerizing and polishing to get to an 870 Police model.

There's a list of all the differences between the two somewhere here, if not check the REM website for this info.

BTW the "P" in 870P stands for parkerized, not Police.

metal trigger mech
Police firing pin and extractor
Dura coat

That will give you the same quality as a 870P
 
Really, wow, learn something new every day. Yet the police comes in a blued version too.
They used to, but never labelled as 870P.

Police is ordnance grade steel and express isn't. Besides the materials is it possible to get the same fit and finish?

All 870s are built on the same receivers and metalurgy. Remington buids the Police Magnums in a separate part of their building for stricter QC and so the parts don't get mixed up with the economy guns.

You can get close to the same fit and finish, but replacing some of the parts is what will make it more reliable. Like a tool steel extractor opposed to an MIM kind. Certain springs in the Police model are of the extra power kind and the mag tube doesn't have the dimples preventing a magazine extention to be added to name a few.

I have the "Home Defense" version with the factory installed mag extension so no dimples.

Metal trigger assembly would be lovely.

I noticed at some places on my receiver there is the odd piece of metal sticking up, especially on the flat top of the receiver, looks like it is unlevel.

There probably isn't much to actually do to the gun in regards to slicking it up since it is pretty basic. Wonder if it would be even worth it to sand it down and kinda clean things up.
 
Ripped from the Remington LE and GOV sales archives ...

Important differences between Remington 870 Police and 870 Express shotguns.

The 870 Express has been an important part of Remington’s offering to the sporting market. It was designed to meet a price point in the commercial market while still providing classic 870 functionality. All of Remington’s 870’s have interchangeable parts, even if they have cosmetic differences. It is also important to note that many manufacturers use the 870 Express platform for their Police / Combat models. Without exception, every manufacturer who utilizes our 870 platform serves to upgrade their system to a more efficient, street worthy platform.

While the 870 Express is still an 870, the best pump shotgun on the market, there are some very important cosmetic and functional differences between it and the 870 Police. To our customers in Law Enforcement, Military,

Corrections, and Security, whose lives depend upon the unfailing performance of Remington shotguns, the Police modifications are of paramount importance.

Synopses of the variances are provided below.

• 870 Police shotguns go thru a special 23 station check list – ranging from visual inspection, functional testing, test firing, and final inspection.

• All Police shotguns are assembled in a “special build area” at the plant in Ilion, NY. This section is secured and serves only to build LE and Military shotguns, with the same factory personnel working at that assignment each shift.

• All parts that enter the “special build area” are visually inspected by hand to ensure top quality and functionality.

• Due to heavy recoil in buck and slug loads, all 870 Police guns have a longer magazine spring which ensures positive feed and function.

• A heavier sear spring is used to generate a reliable, positive trigger pull between 5 and 8 lbs.

• A heavier carrier dog spring is used to ensure when the carrier elevates the shell, it will be held there until the bolt can push it into the chamber. This ensures positive feeding when using heavier payload rounds.

• Police shotguns do not have an ISS (Integrated Safety System) which is a locking mechanism on the safety of commercial shotguns. This type of locking mechanism can cause delay to an officer who needs the weapon but does not have the appropriate key. LE shotguns have the standard, proven, cross bolt safety.

• The fore-end on the Express model is longer and not compatible with many police shotgun vehicle racks.

• The Police shotguns utilize the heavy duty SPEEDFEED Stocks and Fore-ends.

• The Express model will not allow for the addition of an extension tube without physical modification to the tube and barrel, which can nullify the warranty.

• The Express model has a BEAD BLAST BLUE finish while the Police models utilize either High Luster bluing or Parkerization.

• The Express model utilizes a synthetic trigger housing while the Police models use a compressed metal housing.

• The Police shotgun barrel is locked down with a “ball detent” system in conjunction with the magazine cap vs. a lesser grade “synthetic magazine spring retainer” lock down as used on the Express system.

• The receivers used in Police guns are “vibra honed” to smooth out rough finishes and remove burrs before parkerization or bluing.

• Police shotguns use machined ejectors and extractors, as opposed to powdered metal cast which are utilized on the Express models.

:)

A lot more than most people expect the differences to be.

• A heavier sear spring is used to generate a reliable, positive trigger pull between 5 and 8 lbs.

Not very reliable if it is between 5 and 8 lbs.

• Police shotguns do not have an ISS (Integrated Safety System) which is a locking mechanism on the safety of commercial shotguns. This type of locking mechanism can cause delay to an officer who needs the weapon but does not have the appropriate key. LE shotguns have the standard, proven, cross bolt safety.

Is that the J lock? Mine didn't come with that, just the normal push safety.

Also what is this ball detent system?
 
The ball detent is found on the barrel ring where the mag cap is ratcheted to so it doesn't come lose. Express models have a different system with an added plastic part fitted into the tube that in conjustion with the inner teeth of the mag cap, it locks up the mag cap securely. The mag cap on Police models are different and have the divets on the rim of the cap to take advantage of the ball detent on the barrel ring.

The 5-8 pound trigger is a lawyer deterrant weight first and foremost. I'm not sure if you've ever used your gauge under duress, but a light trigger pull on a defensive gun is a dangerous proposition. If that's a factor, the sear spring can be replaced for a wingmaster one without messing with the hammer and sear engagements. ... other than that, the hammer and sear can be stoned to a crisper trigger break. It's how some of us turn a buck. :)
 
Hmmm that ball detent sounds pretty cool. I suppose you will need a new cap if you buy a police barrel. I am sure that would be even harder if you have the mag ext. The plastic part on the mag extension feels like a weak link in my books.

I always find that a plastic trigger feels more sloppy than a metal one. As for the 5-8 I was referring to the fact that they spend so much more effort on the police model and there is a +/- 1.5 lb difference in trigger pulls.

So smoothing out rough areas.
Metal trigger assembly.
Machined firing pin and extractor.
Parkerized finished.
Then essentially you have a poor mans aftermarket 870 police.
 
One more thing I'm sure of that I don't see on REMs list above is that the Police models have heavier shell latches.

You're missing a half dozen higher power springs.

Consider the 870 Express the Camaro, good, powerful, works alright. The Police is the Corvette. Subtle differences matter...

The parked 870P's aren't labelled with "870P" either... It says "870 Police Magnum" on them. The blued version that I just sold on this site less than a month ago (NIB) was marked exactly the same way and sported the same high polish blue as the Wingmaster line of shotguns... Unless Remington has VERY recently taken them out of their lineup, they are available in a blued version... Just fyi.

The blued version you recently sold, was it stamped "870 Police Magnum" like this one in the photo? I haven't seen these produced new in a very long time. Maybe available through special order?

... and I missed your sale. I would have jumped on it. :)

Yup, exactly the same... It had nicer wood than the one in the pic though... Not a scratch or blemish on either the bluing or wood. Funny you didn't see it though because it sat on the EE for about a week and half before it finally sold. Really hated to sell it 'cuz it was truly the best looking 870P I've ever seen. But hey, as your sig line says "easy come, easy go"...

Oh yeah, almost forgot... Not special order when I purchased it. I saw it on Epps' website under the "Remington" section and took a chance with the purchase - sight unseen. I was pretty happy when it arrived on my doorstep...

Must have been when I was away incommunicato from home, working. That is too bad I missed it.

The one in the photo has served me well though. It's an old one, I'd like another any day.
 
No, not the same one Ardent. I can tell you for a fact that I wouldn't have sold it if it was the 14" version. The one I had was an 18" one (with front bead) exactly as in the pictures. It was factory new production in the original box (and specified an 18" OEM barrel on the box end sticker)...
