Remington needed to be able to compete on the low end against Winchester and Mossberg.
The problem is, Remington still uses the much more expensive to make forged and milled steel receiver, while the Winchester and Mossberg use cheaper to make cast aluminum.

So, in order to cut the cost of the 870 Express models, Remington went to the plastic trigger guard, the rougher finish, and the new magazine tube retention system.

The older tube design still used on the Wingmaster and Police guns, uses a steel cup washer to hold the spring in the tube, with a spring-loaded plunger retaining the magazine cap on the end of the tube.

The new Express system has two lugs, or "dimples" pressed out into the tube near the front end. A plastic bushing interlocks with the dimples to lock the bushing into the tube, and the front of the plastic bushing has "teeth" that grip burr-like projections inside the magazine cap to keep it from unscrewing.

There is no expensive steel cup washer, spring-loaded plunger inside the barrel ring, and a much cheaper to make mag end cap.

All this holds the cost down so the Express can compete.

The lockable safety is a special safety button that can be locked with a special "key" making the gun unable to be fired until the safety is unlocked.

The safety is "PC" but get used to it. You will see more and more of this on guns until we put the brakes on the lawyers who are suing everybody in sight. Remington is just following the trend of the rest of the gun companies, most of whom either have a lockable safety, or are working on one.
Nobody likes the safety, but in order to hold off the sharks, ya gotta have it. Look at this like a gun version of air bags and seatbelts.

The new style Express magazine assemble with "dimples" has nothing whatever to do with "PC" and everything to do with cost and competition.
There are those who think the dimples are "PC", but if Remington doesn't want "Civilians" having the "evil" magazine extension, why do they sell all comers the 870 HD and Marine model with the magazine extension factory installed???????

Again, it's all about cutting cost to allow a forged and milled steel receiver gun to sell at a price comparable to a cast aluminum receiver gun.

Leaving aside the issue of the integral lock, Remington shows its PC side in other ways on the 870 Express (and others of the 870 line). Most notably, you can see it in their policy regarding the TacStar sidesaddle accessory.

(I'm going to plagiarize from my own 870 article):

If you have an 870 Express or an 870 Wingmaster, you're going to have some trouble installing the Sidesaddle. The slide on the Express and Wingmaster shotguns is too long -- about 1.75" too long -- and so that excess will have to be chopped off if you want to use a Sidesaddle.

There are a few ways around this nice little modification. First, you can buy a Surefire Responder (weapon-mounted light) for around $200-250 -- the Responder does not have any clearance problems with the Sidesaddle.

But let's say you don't have an extra $250 laying around to buy a Responder. Fair enough, especially for 870 Express owners who probably paid less for their gun than the purchase price of a Surefire.

Where Remington's PC stripes really come out is if you try to buy a special shortened slide from Remington to address the above problem. Remington will only sell the shortened slide to owners of the Remington 870 Police model. Call them and ask. I did.

There is no reason why 870 Express and Wingmaster owners should not be sold something as harmless as a shortened slide so they can use a Sidesaddle. The shortened slide is available to 870 Police owners. You can draw your own conclusions.

It is also my understanding that that 870 HD retains the magazine tube dimples. I can't even find the 870 HD on Remington's website (have they dropped it?). The closest thing is the 870 Synthetic (18" plain barrel):

Mag capacity is only 4 ... no mag extension from the factory.

And note the nice blurb at the bottom of the page: "The Model 870™ Express® is intended for personal use and will not accept law enforcement accessories." Nice, eh? :fire: This blurb is only present on the 870 Synthetic 18" barrel product listing -- you will not find it on the 870 Synthetic 26" barrel or the "regular" 870 Express pages. Ask yourself why they'd put this blurb here (on the most defense-oriented 870 they have listed, save the 870 MM) when no "law enforcement accessories" will fit the "regular" 870 Express or Wingmaster.

Lastly, IMO the integral lock is further evidence of Remington's kowtowing to the hoplophobe community. Where are the integral locks on Winchester Defenders, Benelli M1S90s or Mossberg 500s?

Based on the above (and more -- ever check on Remington's policy on the 700 Police rifle?) I added Remington to my boycott list.

NB. TacStar, probably in response to peeved Remington 870 owners, came out with a four-shell Sidesaddle which fits the Remington 870 Express and Wingmaster without modification. But you lose two shells in the process. Notice it was TacStar that had to solve the problem, not Remington ....

Does the Marine Magnum have the shortened slide like the Police models???

April 22, 2003, 03:13 PM
Remington doesn't have either a shortened or long "slide".

Remington commercial guns have a sporting type FORE END or hand grip that extenders farther back. Police guns have a shorter hand grip just like almost all older shotguns used to have.

The newer commercial fore end will partially cover the loading port and will hit a sidesaddle, preventing the slide from moving far enough back to operate the gun.

The commercial hand grip is an appearance item, covering more of the exposed mag tube, making the gun LOOK better, and it prevents getting your hand pinched between the receiver and the fore end. Remington decided this looked more stylish than the older "Corn Cob" fore ends used on older guns.

The Police guns still use a shorter, original-type fore end mostly because years ago the police started using lockable shotgun racks in the patrol cars. These racks lock around the receiver and have an section that fits between the fore end and the receiver that prevents the slide from being operated while the gun is in the rack.

This has little to do with side saddles, since Remington has used this fore end on the 870 Police since 1950. The side saddle is a fairly recent invention, and in truth, most police departments don't use them anyway.

If you have an commercial 870 with the long fore end and want to use a side saddle, simply cut the rear of the fore end off!!! This is a common alteration when converting an older Wingmaster to an HD gun. There's no need to buy a short police-type fore end.

As to the HD and Marine with a factory magazine extension. The HD designation has apparently been dropped, and Remington now just lists it as an 18" Express. I can't find a catalog number for the Express 18" with the mag extension, but it is available.
The STANDARD 18" Express does have the "dimples" since it's just a standard Express with the standard magazine. The factory extension Express doesn't have dimples.

As to the statement that Remington Express guns won't accept Law Enforcement accessories: This is just a statement of fact, in the order of a "head's up".
The reason they don't put the "No LE gear" disclaimer on the other Express guns, is that people who buy the HD-type gun MIGHT figure they CAN use LE accessories, and Remington wants to make sure they know there's a reason the Express HD is so much cheaper than the Police.

Remington designed the Express for the targeted consumer: a sportsman.
Probably 99% of the purchasers of the Express guns are hunters, many of whom probably don't know magazine extensions and side saddles even exist, and few of whom would ever want one.
Again, 99% of the sporting Express gun buyers will never be concerned about LE gear, so no disclaimer is necessary.

Simply put, Remington didn't design the Express to be a combat or police gun, they built it for sports shooters who wanted the cheapest gun possible from Remington.
The 18" barrel Express is Remington's "average" home owner's idea of an HD gun: A cheap, basic, no-frills shot gun. Most of these people don't use extensions or side saddles either. Again, they just want the cheapest gun possible.

Remington's plan was that the Express would be the "budget priced" gun to compete against Winchester and Mossberg's commercial-type guns.
The more expensive Wingmaster would be for those who want a top-of-the-line or specialty gun, and the Police model would be for those wanting a full-blown combat gun, with all the "bells and whistles".

As to the "PC" safety. All new guns come with some kind of trigger lock, and MOST gun makers are working on some kind of integral lock device, or other safety feature. Many new handguns have a built-in lock device and the rifle and shotgun makers are moving that way.
This is just an unfortunate fact of life in the lawyer-ridden culture of today.
Anybody seen the new Mossberg DOUBLE-ACTION pump shotgun?
There are rumors that Winchester is working on some kind of action lock system for their rifles and shotguns.
Anybody seen the safety button on the Winchester 1894 Lever-actions?
How about the safety buttons on the Marlin lever-actions?

I'm NOT saying that "PC" isn't running rampant in the gun industry, I'm just saying that Remington DIDN'T design the Express to be a PC gun. They never intended it to be a police-type gun, and the HD model was an add-on for home owner's.

They designed the Express to cut costs so they could stay in the low-end shotgun market, and they added the lockable safety to hold the sharks at arms length.

Want a cheap gun? Buy an Express.
Want a Police gun with all the neat accessories? Buy a Police gun.
Don't want an integral lock? Sorry, get used to it, their coming every where, along with the ultimate "PC" gun, the "smart gun" that will decide FOR YOU if you can use it.

Thanks for your explanations. It is clear to me that you are very well versed in Remington shotguns.

Note that there are other ways of solving the problem of Remington's over-long fore-end. Beyond laying out $250 for a Surefire Responder, one can buy the 4-shell saddle from TacStar. I have a Responder for my Benelli but it's not like I want to put a $250 light on a $200 gun. :(

However, your well-intentioned essay has not explained why Remington will not sell the shortened fore-end to non 870 Police owners. If in fact it was cosmetics, there is no incentive to restrict distribution. I suspect the motivation is not just cosmetics.

I also refuse to roll over and accept the integral lock on Remington longarms. I don't like it and I refuse to just accept them as a "fact of life".

But in particular, I don't like Remington's integral lock. John Farnam reports incidents in his shotgun classes of 870s locking up by themselves (without the key). On a defense gun, this is an appalling "feature". I do not want such poor execution of an internal lock -- get off your duff Remington, if you're going to install an integral lock, make it work correctly! :fire:

The Mossberg 500 DA is an abomination. Mossy's reasoning was to provide commonality of trigger pull between the officer's sidearm (a DA revolver or Glock pseudo-DA trigger). IMHO it is a poor idea.

I don't know anything about Marlin or Winchester lever rifles. I'm only talking shotguns. And maybe Marlin and Winchester have got the PC bug too, in which case I'm more than happy to add them to the boycott list.

In sum, THR readers can draw their own conclusions as to Remington's motivations. Given their restriction on availability of the fore-ends, I see no motivation beyond deprivation of the non-LE/military market of defense-minded accessories.

It saddened me to put Big Green on the boycott list. Dad worked at duPont, Remington's former parent, for 25+ years. I believe at one point it was possible to get Remington stuff through the company with his employee discount. Those were the days. :)

To me there is little question that Remington has got the PC bug. Until they lose it, they've lost my business.


April 22, 2003, 04:49 PM
Remington has always been a little "hinky" about LE gear. They always stamped "Law Enforcement Use Only" on their folding stocks.

I think there is indeed, an element of PC at Remington, which I blame on the current atmosphere of suing everybody with more than $50.00 in his pocket, and on the foreign ownership of Remington. Remember the British owners of S&W?

I DON'T understand why Remington won't sell a wood or plastic fore end to all comers. I'm sure there is SOME kind of Corporate "Bean-counter" mentality behind this. If Remington will sell "civilians" a Police shotgun, why not a piece of wood?
On this, I have no idea.

As for the PC lock, the average gun owner couldn't care less about this, if they even really notice it, and I doubt if any but a tiny percentage ever actually use it.
I won't, and that's why I bought a police gun.

BUT, Remington isn't targeting commercial guns to people like us.
These days, if you make egg beaters, and have $150.00 in the bank, lawyers are targeting you for a fast raid. Even better if your company is a maker of "evil" products.

As much as I dislike these safeties, be assured that if I owned a gun company, my guns would have locks, just to CYA.

As for the PC Express, Remington really didn't design it that way to stick it to people who wanted to modify it to an HD gun. They simply didn't build it to BE modified, in keeping with the targeted market of sporting shooters.

It was all about price and completion, but later when push came to law suit, it was also "Oh, so PC".

As for a huge foreign owned corporation like Remington, their bottom line could care less about selling a few bucks worth of fore ends to to a small hand full of obscure people. So, if their business practices PO us, their bottom line won't detect even a ripple.

THe longer fore end is actually an aid to shooting, IMHO.

as soon as i get some money, i'm going to put the youth model stock and pumphande on my mossy so i can have more pumphandle area.

If you don't like the new locking safety, you can get a replacement non-locking safety ( from Wilson Combat. I have one on my 870HD.

A couple things....

First, an 18" barreled 870 Express with zero addons and mods is still one d*mn good "Serious" shotgun in trained, cool hands. Lots of folks will get these and be well protected thereby,if they practice and learn the weapon. That's the same for every weapon, from nuke to rock.

Us fans and gearheads tend to obsess about the gadgets and gimmicks, The best accessory is still lots of ammo. BA/UU/R.

As was said, those who want a bare bones HD shtogun should think about this Express. Those who want the bellsnwhistles should go with the LE models or heh,heh, older turnins. Meanwhile, I'll keep looking for old WMs.

And, good people, if a good hand with an 18" barreled Express cannot control a situation, chances are a more "Evolved" weapon and that operator won't either. Expertise and proficiency beat hardware hands down.

April 22, 2003, 07:34 PM
I have an older "Special Purpose Magnum" 870. It has the dimples on the mag tube - are these just Express 870s with a different name? Are there any differences in the SPM and the Express?

"Remington's plan was that the Express would be the "budget priced" gun..."

Ain't that the truth. I bought a 870 Youth Express. It's setup for screw-in chokes but Remington only provides one choke tube. Sorta like buying a car with one tire and three empty rims. Even though it's got that god awful PC safety it's still been a great bunny buster. -- Kernel

If Remington will sell "civilians" a Police shotgun, why not a piece of wood? Remington's written policy is that the LE guns only be sold to LEOs with letterhead. It's not really enforceable, but we are talking about intentions here. If it were up to Remington, we would not have access to the guns with the "evil" features.

As for the PC lock, the average gun owner couldn't care less about this that is, until it locks up when it's not supposed to... like in the middle of a shootout.

Oh, if anyone cares, Mossy sells both the sporting and tactical fore ends to anyone who wants it.

April 24, 2003, 09:23 AM
On my HD gun, it took me all of 45 minutes to grind out the dimples and polish the mag tube with a Dremel. The Choate mag extension I installed works just fine.

On all of my Remington shotguns, I installed old style safeties. Takes about 5 minutes when you're cleaning your trigger assembly. (You do clean your trigger assembly, don't you?)

On the HD gun, I use a four-shot side saddle because I actually like the longer fore end. I hunt with my other 870s, and when I pick up my HD gun, I want it to feel the same as the others. To that end, all my Remingtons have the same amount of extension at the butt pad.

The dimples and locks are annoying, but it's worth the trouble to modify them.

If reliability of the lock is an issue, why not defeat it with superglue or loctite?

April 24, 2003, 05:48 PM
So much easier to pull the old safety and install a regular one that costs no more than $10. Wilson Combat ran a special on old-style safeties a while back ($4 each), and I bought up a bunch.

Now, I have no doubts about my safety. The gun is either safe or it's hot, and I know the difference.

April 25, 2003, 07:51 AM
The dimples don't concern me as much as the safety and the continuing downward spiral of Remington's quality control.

Current production guns are discouraging in their fit, finish and general appearance compared to the products of even only a decade ago. A recent test fire of a new Remington 1100 Sporting revealed a gun that couldn't hold a candle to the Remington 11-87SC that I owned several years ago (and deeply regret selling).

If I want another Remington I'll but it used. The older Remington 870s, particularly the trap guns, will stand proud on the rack even beside the high grade over/unders. The only trouble is that good condition 870s are becoming harder to find on the used gun shelves.


July 9, 2003, 07:06 PM
Saying that you desired to keep the 870 Express magazine tube avec dimples, couldn't the mag tube, spring retainer washer, mag cap, detent and detent spring of non-Express parts be used in place of the Express components? Wouldn't this then avoid the drilling/grinding removal of the dimples from the Express mag tube and allow the installation of the aftermarket accessories(mag extenesions) without the hassles. This would also allow the re-install of the original Express components without questions should the owner ever want to resell/private sale of the shotgun(hey, what are those little holes all about?!?). Just thought I'd ask?

Hey Justin, will you be at the Shotgun match up at Ontalaunee R&G on 7-20/03? It's billed as the Notheast Regional Practical Shotgun Challenge. Two classes(Pro & Sportsman) with two divisions(auto & pump). Haven't seen you in a while and hope to see you there!

The more I read the boards about the 870 the more it makes the 8 shot, no lock, Winchester Defender look better every day.

I didn't have to cut anything off the forearm to install a Tac Star 6 shell Sidesaddle in 2 minutes.

Lets look at the pros for Winchester:

- 8 shot vs. 4 shot
- No stupid lock vs. Stupid Lock
- Sling mounts vs. No sling mounts
- Removable front TRUGLO® fiber optic sight (and a bead) vs. Bead
- Will take a 6 shell side saddle without modification vs. Cutting a piece of the gun off!
- Better Finish (just look at the two side by side)
- Winchester has faster and smoother action (try it before you start yelling)
3 SHOTS: .56 of a second ... those numbers sum up the Winchester Model 1300 Speed Pump™ line of shotguns. Though you may not care to shoot as fast as our R&D shooters, you’ll still get follow-up shot speed you’ll appreciate. Speed Pump shotguns are renowned for impressive follow-up shot speed thanks to inertia-assisted pumping from a proven rotary bolt system. Yeah that is hype from the Winchester website they also claim they make the fastest semi, but thats another story...
- And in most places I have looked the Winchester is cheaper.

Don't tell me I can't get accessories for a Winchester. Tac Star has the 6 shell sidesaddle, Surefire has the light mount etc. Length or Pull, Drop at comb and Drop at Heel are all identical!

Reliability / longevity?? I have a 1300 Defender with the aluminum receiver :what: and it has over 18,000 (yep thats eighteen thousand) 12 gauge shells through it without a single non operator induced glitch (I am sincerely rying to make the thing fail, once well over 1000 before a cleaning). They are both incredibly reliable and will outlast your red meat eating and prostate destroying self.

I understand that Remington made the most popular pump gun in America but Ford makes the most popular vehicles and everyone knows Toyotas are a better value and more reliable. Trust me I owned a Ford and a Toyota...

eeh. defenders also have a short forend, which can pinch bodyparts between it and the action.

you're comparing apples to oranges, as the defender is the equivalent to the 870 police. the short mag tube 1300s are more analigous to the expresses and wingmasters.

The police does have sling swivels, as far as i know.

As i said before, the wingmaster style forend is a better system, because it affords more gripping area.

beads are just fine for most purposes, and those plastic fiber optic sights can be added to the 870 for 30 dollars or so, if you feel you should have one.

were i right handed, i'd have no qualms about acquiring an 870, but their safety, manual of arms, and lifter that covers up the loading port are pretty big negatives (ones that go for the 1300 as well) in my estimation.

I don't know about your defender, but my fathers defender is noticeably less smooth than his wingmaster, and is about on par with my mossberg.

I can do you one better ... haven't attended a single Easton match yet this year and only one Sciota match. I haven't taken a day of vacation from work ... I think the two are somehow related. :( Best of luck house hunting!

On the origin of my post though, wouldn't the parts I listed do as good as drilling/grinding out the "dimples" on the 870 Express's mag tube?

I can't say I've had experience with your idea but I can't think of a reason why it would NOT work. My dad's 870 Express remains stock and he doesn't really care to install a mag extension.


July 9, 2003, 11:17 PM

"On the origin of my post though, wouldn't the parts I listed do as good as drilling/grinding out the "dimples" on the 870 Express's mag tube?"

Sorry, won't work.

The Remington magazine tube is brazed in place, and is non-removable. Since the tube has the dimples, having the other parts won't help.

As to the Winchester/Remington choice: This is strictly a matter of personal preference. I doubt the average shooter could wear out either.

The Remington has an edge because it's THE American Police shotgun. They literally OWN the police market.
Very, very few, if any Police departments buy the Winchester. The Remington 870 is so good, and has such a great reputation with police agencies and military units, that they have a "mortal lock" on the police shotgun market.
Mossberg sells some, Ithaca sells some, Winchester sells about NONE, and Remington laughs all the way to the bank.

This reputation, (and actual performance under the harsh conditions of police/military usage) has Remington in such a position that no other shotgun maker need apply.
Some years ago, Smith & Wesson was attempting to expand it's then ownership of the police handgun market into the shotgun market. They made a big push in attempting to break into the market with the Model 3000 Howa-made shotgun that was a close clone of the 870, at a lower price. Remington ate their lunch, and S&W slunk back to the pistol market.

Winchester "surrendered" the police/military shotgun market when they discontinued the Model 12. When the Winchester 1200/1300 hit the market the police lost all confidence in Winchester shotguns.

All this isn't to say the Winchester is no good, just that few American police agencies trust it. The few that have tried the post- Model 12 Winchester were very up front in their total dissatisfaction with it's performance, and quickly went back to the 870.

Again, for a civilian shooter the choice is totally personal preference. If you're a police or military agency buying shotguns, Winchester's past performance with the 1200/1300 is the kiss of Death.

July 10, 2003, 02:18 AM
... the removal of the detents/dimples from the Express magazine tube, the previous ratchet/toothed spring retainer would be somewhat useless for the intended purpose, wouldn't it? With the dimples removed, there would be no manner in which the mag tube spring retainer would be prevented from simply spinning within the mag tube itself, as the mag cap was screwed in place, thus no longer providing any type of "ratcheting" action. This would then no longer retain the mag cap as the spring retainer(Express dimple type) would simply spin with the cap as it was tightened and would/could also simply back off.

The barrel on my 870 Express has the recess for the detent & detent spring, which should allow the usage of the original type mag cap(with the split cup style mag spring retaining washer). I would think this would be a better solution than using an Express style mag cap, should a mag tube extension be removed once the dimples are no longer present. Just seems logical from the explanations and observations available.

BTW, thanks on clearing the manner in which the mag tube is mounted in the 870 series. Funny thing is, Numrich/Gun Parts lists the mag tube as being available as serperate items(on their web site). Thanks again!

July 10, 2003, 12:52 PM
The "best" methods of dealing with the Express is to either leave it as original, (no mag extension), or convert to the Wingmaster/Police-type mag system.

Every Express barrel I've seen had the hole for the mag cap retention spring and plunger.
In my opinion, if you want to change to the mag extension, and then change back, the best method is to go ahead and buy the Wingmaster mag cap, spring cup, and retention spring and plunger.

You will have to either buy or make up a staking tool to stake the spring and plunger into the barrel support ring, but when you've finished, you have the complete flexibility of the Wingmaster system.

As for the sale of mag tubes by parts houses. Yes they do, but the factory mounts the tube by brazing them in place in an electric oven. This requires some type of holding and aligning fixture, there's the danger of damaging the heat treat or warping the receiver, plus the need to refinish.
I believe the factory considers the tube to be a factory-only replacement item.

All these mag tube assembly problems are the minus side of buying the cheaper Express gun.

Contrary to popular "urban legend", the Remington move to the Express tube assemble was COST driven, not PC. It's simply cheaper to use the plastic parts, formed cap, and dimples than the more expensive cap, steel cup washer, and most expensive of all, the hand labor needed to assemble and stake the retention spring and plunger. That requires human hand labor and that's always expensive.

Again, your choices are:
Stay with the Express non-mag extension.
Change to a mag extension, and stay with that.
Modify the gun to a Wingmaster/Police assemble so you can change at will.
Or, cut to the chase and buy a Police gun or used Wingmaster.

July 10, 2003, 01:16 PM
A quick search on turned up item 080-870-205, I believe thats the proper staking tool for the barrel detent. The detent (767-000-160) and spring (767-000-154) also appear to be available. Magazine cap: 767-253-750, spring retainer: 767-916-570

Is there good way to put a sling swivel on this synthetic stock?
